How to get a 'white' answer when you use 'if' statements in a table

I use a table for an invoice where an element is classified, but more can be shipped as ordered. I have figured out formcalc expression where I can get a 0 in the column "out of stock" If the delivered quantity is more than the ordered article, but I can't get rid of a value of 0 in the rest of the column out of stock when all information "shipped" columns "orderly" and. Try to get this column blank if there is no order or shipping information.

So far, it works for the math part. Don't know how to write an 'empty' in the calculation


If (Sum(ordered-shipped) > 0)

then backordered = Sum(ordered-shipped)

ElseIf (Sum(ordered-shipped) < 0)

then out of stock = 0


Any advice will be greatly appreciated. Thank you!

Have you checked the patterns listed for your numeric field in the object palette?

This could be the cause for the zero. I tried on my system local and if I assign null, he demonstrated an empty value.

  • How to get out a window, when you use the main screen?

    When I'm in the MBR to 8 window and I opened a program like IE, how to close to return to the main screen. Some other icons are the same thing. I'm looking for a way to close it and return.

    I know that I can go to the lower left window, but did close these windows? Hope this makes since. I think that if I click on music it does the same thing. I can't end this one. I can find a break and other things.

    Bring your cursor to the top of the standby screen until you see the hand and then click and drag it to the bottom of the screen... Who's going to close an application and take back you to the start screen.

    Press windows + C which will open the charms of the right side

    Press windows + key X that will open a menu of useful type administration programs

  • How can I customize the toolbar when you use the browser of the attribute

    In CVI 2012, changes in the toolbar depending on the environment, for example, it is different to the source window and the user interface editor. The toolbar can be customized using the Options menu / toolbar...

  • Why do I get an Error Message When you use "Embed" to access a file png (for an asset class)?

    I use Flash Builder and Starling to create a new project. I created the initial classes for Starling running. Everything works fine.

    However, I created a class of assets (that will manage all the assets of the project) and I get an error message when you reference the png file. This png will serve as the main screen for the project. See below:


    Import starling.textures.Texture;

    private static var MainScreen: Class;

    public static var MainScreenTexture:Texture;

    MainScreenTexture = Texture.fromBitmap (new MainSreen());




    I have the file in a folder called 'active' which is in the main project folder. Why I get this error?

    Hi Ricky,.

    ·         You are able to install programs and drivers?

    ·         What is the motherboard Chipset Drivers file extension?

    You may experience this problem if the installer has downloaded file is corrupted. Follow these methods and check if that helps:

    Method 1:

    I suggest to download the drivers to a different location on the computer and see if you can install it from there. I suggest you to install the driver Chipset in high Mode and check if it installs.


    Method 2:

    Try to update your BIOS and then install the motherboard chipset drivers and all other available device drivers check if you get the error message.

    Warning: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  • Determinations of web OPA shows white screen when you use the data model


    I use Oracle Policy Modeling on windows 7. I use embedded apache tomcat to test.

    I have started a new project, added a simple rule:

    [b1] the parent is eligible for the benefits of compassion so

    [b2] parent has a child

    I chose 'Build and Run' selected web determinations, work very well.

    When I added a data model, created two entities, parent-child, and the child is contained in the parent as to-many, then ran the project, it won't work any more. The section that says:


    is absent.

    I also tried to open an example of "MembershipDemo" that comes with OPM, same problem.

    Any ideas how can I fix?

    Thank you very much

    Looks like you have probably changed the Boolean value "the parent is eligible for compassionate care benefits" from the global to the parent. This means that is no longer a goal because it is a single Boolean value that can be determined, it is now a Boolean value for each parent in the rule template.

    The goal that presents itself as the first screen in your interview display all the high-level objectives - that is, all objectives at the global level.

    Some possible solutions to get a goal for your interview may are:

    1. If you try to determine cbb for 1 single parent, then you probably shouldn't introduce a parent entity, use the global as a parent

    2 introduce a global "all determined the eligibility of the BCC of parents" trying to see if "the parent is eligible for compassionate care benefits" is known to all parents

    3 decide which is the highest level (s) for your interview and to introduce these Boolean values to the global level.

    Hi all

    create the table SAMPLE_ITEMS

    (ITEM_NO, varchar2 (10))


    Number of QTY_SUM1

    Number of QTY_SUM2

    Number ITEM_QTY,

    Number ORDER_QTY,

    Number ITEM_AMOUNT,

    Number of SALES_AMOUNT


    insert into SAMPLE_ITEMS values ('AAA', ' 28 / 04/2014 ',-88, 0,475,262,-123.45,-1188);

    insert into SAMPLE_ITEMS values ('AAA', ' 28 / 05/2014 ', 0, - 122, 475, 262, - 10.234,-1647);

    insert into SAMPLE_ITEMS values ('AAA', ' 16 / 06/2014. ', 0, 0,475,262,-80.59,-135);

    insert into SAMPLE_ITEMS values ('AAA', 19 December 2014 ', 0, 0,475,262,-42.29,-67.5);

    Setting out with my own query,


    Every time I question as code

    Select * from SAMPLE_ITEMS

    where DELIVERY_DATE between April 28, 2014 ' and 19 December 2014 '-> they must pass as a parameter

    I need to get only one line



    Note; Please do not use MAX for Date and do not want to display Date columns in the result

    Note 1: I want to choose DELIVERY_DATE in select it also and only get a line like above the expected result

    SELECT item_no

    SUM (qty_sum1),

    SUM (qty_sum2),

    SUM (DISTINCT item_qty),

    SUM (DISTINCT order_qty),

    SUM (item_amount),

    SUM (sales_amount)


    WHERE the DELIVERY_DATE BETWEEN TO_DATE (28 April 2014 ', "dd/mm/yyyy")

    AND TO_DATE (19 December 2014 ', "dd/mm/yyyy")

    GROUP BY item_no;

    I will get


    AAA             12/19/2014                         -88                 -122                475                262                       -256.564              -3037.5

    OK fine, I want to choose DELIVERY_DATE as if so I'll have all the lines, but I want to only show one as shown above

    Because I do report discoverer in Oracle Apps, without taking the DELIVERY_DATE of the select query, it is not possible to move the date as a parameter

    Can you please help me how to do this?

    Thank you

  • How to make an advanced search when you use adobe reader software in a firefox window?

    I used to be able to do an advanced search in a tab in firefox, but when I updated firefox to version 17.x 33.0 version, the interface has changed and I cannot figure out how to do more.

    Finally, I realized that a simple search can be made with Ctrl-F, but I would get the Advanced Search Panel.
    When I use internet explorer, it has a binoculars icon that will open the advanced search. Firefox doesn't have this.

    In addition, Firefox put up their own PDF Viewer with version 19.0; It's no longer using the Adobe Reader plugin.  See

  • How to install the PFB fonts when you use Windows 7 64-bit?

    I got a new computer with Windows 7 64 bit. But when I copied the fonts I used on the old computer, PFB fonts do not work any longer.

    The former ATMF program doesn't work so how can I now install PFB fonts on this computer?


    I hope that you did not try to install the old software of Adobe Type Manager . If you did, you may need to completely reload Windows if you cannot restore your system to its state before you try to install this software!

    Assuming that you did not this fatal error, the method to install Type 1 fonts, which each consists of a .pfb and .pfm file is as follows:

    (1) copy the .pfb and .pfm files in a single directory if they are not already available.

    (2) select the .pfm for the fonts you want to install files.

    (3) right click and select install which will then install the fonts on your system by copying the .pfb and .pfm files into C:\Windows\Fonts directory. Do not drag - move these files! If you do not want the font files themselves reside in the C:\Windows\Fonts directory, when you right click on the file, select install as a shortcut. This installs the police but he refers to his current location.


  • How to change the search engine when you use the functionality of Firefox Home button Search?

    In Firefox itself, I have configured duckduckgo as my default search provider.

    But when I use the host Firefox search button it is always defined on google and I don't see any possibility to change that?

    I love the Firefox Home button Search (or whatever we call it) otherwise, but it's annoying that it does not use the default Firefox.

    I use the Google Launcher now.

    Hi mrt181, it is planned to use the same search engine as in firefox - however, there is a bug at the moment, so it does not apply in all situations.
    usually, it will be enough to change the default engine in firefox back once to work around the problem in the search widget and get the same as set in the browser search provider.
