  How to disable certain fields in the form of a calculation with a checkbox for the fields.

  In Canada, we have taxes

  I create a form that allows them to calculate a total

  

  I need to be able to turn off all of those taxes to participate in the calculation and to their field visible should be 0

  I was thinking about using a check box (when the checkbox is enabled (Yes) the tax is calculated, unchecked (Off) the tax is not calculated and visible field should show 0 or anything...)

  I really need help on this one, I am a complete newbie...

  Note that the second tax is calculated on the sum of what the first tax Add (tax first is pan-Canadian tax (all provinces).

  The second tax is never only use (Quebec only (in addition to one Canadian)

  Sometimes to sell outside Canada - no tax at all is calculated...

  What should I do?

  Yes, it's just the JS...

• How to set a field in a form of DML to only display?

  It seems that it would be obvious, but I can't figure out how to set a field in a DML form read-only.  Thanks for all the ideas.

  The most obvious thing is to define the type of item to display only. Save Session State to Yes if the value of the item is required in after not submit treatment or if the value is only for display on the page.

  Alternatively, if you want the element to appear as a normal text control, but do not be modifiable, set the item text field and the custom attributes type to readonly .

• How I afford two fields and round?

  I need an average of two fields and then round the whole number closest. The two fields each will always have a value.

  If someone could help me out, I would appreciate it.

  T.

  Assuming you want it's a custom script calcuation for a field, it might look like this:

  Custom calculation script

  (function () {}

  Get the field values as numbers

  var v1 = + getField("text1").value;

  var v2 = + getField("text2").value;

  Set the value of this field to the average, rounded

  Event.Value = Math.floor ((v1 + v2) / 2);

  })();

  More information about the Math.floor method can be found in any decent JavaScript reference.

• How to add two fields and show the result in a third

  All,

  What a transformation I use here to accomplish the tasks?
  
  Any help is appreciated.
  
  Thank you and as always this forum is useful and hellpful.
  
  Concerning

  Hello
  instead use Expression operator, of the transformation link FIRST_NAME and LAST_NAME group attributes of this operator and for the output of entry attribute specify expression as

  FIRST_NAME || LAST_NAME
  

  (it is preferable to use the expression builder that correctly adds the name of Group of entry attributes)

• How to combine two PDF files without form fields-building

  I have two PDFs with form fields in each. Someone else created the documents. Some fields were untitled and so were given names as "not defined" in each document. However, some of these fields contain different information in each document. When I combine the document, these fields mix and incorrect information to in some areas.

  For example, there is a blank field in the doc A, entitled "indefinite". In the doc B, there is a field with "johnson" titled "indefinite." When I combine, "johnson" appears in the empty field.

  Is it possible to combine the documents without the combined fields?

  The code must be placed in a stage of "Execute JavaScript", you will find under more tools in the Edit Action window.

  Here, you must also add a step to the Sava.

• updated two fields with a form

  I'm trying to update two tables mysql to a form.  The page includes the following:

  "A stock" quantity (from table A)

  A text form field (where I entered the used inventory)

  A drop-down list of article for "the inventory B' (from table B)

  I want to be able to enter a quantity in the text field and subtracts it A inventory and added to the inventory B.

  For example:

  Apples. (Table A)

• How to subtract two table of 1 d (uint16) same size

  I need to remove two 1 d (uint16) same size table. with output as follows...

  x - y = result (EXPECTED)

  5 - 2 = 3

  4 - 0 = 4

  0-4 = 0

  If the difference is less than zero value must be zero. Currently, if I use the digital subtraction... I get...

  x - y = result (OBSERVED)

  5 - 2 = 3

  4 - 0 = 4

  0-4 = 4

  2 - 3 = 1

  Thank you

  Hello rajxabc,

  I don't know why you expect whole math unsigned to produce a 0 in the script show you below.  The U16 ends actually spent 0.

  Thus,.

  0-1 = 65535

  0-2 = 65534

  0-3 = 65533

  

  If you want to change the standard behavior of the unsigned integer math, you need to create a special algorithm for this, produce something like:

  

  There are a number of ways that you can accomplish this, but at the end of the day, I don't know that I would be the label none of them "expected."

• How to join two fields with slightly different data

  I have two columns, I need joined, both keep the columns of numeric data, but are of type varchar2 (6). The problem is that one of the columns keeps leading zeros to ensure that all 6 characters are used, but not the other. And columns preserve leading zeros may vary how many zeros are in the number-based computing.
  
  For example, the column with zeros can contain the number 4200, which would mean that he would remain with 2 zeros as 004200. Or it could contain 320, which means that he would remain with 3 zeros as 000320.
  
  The other column that does not have leading zeros not only keeps the number, so, in the example above, it would keep 4200 and 320 respectively.
  
  Can someone help on how to join these columns so that they match? I guess I have to delete the zeros in one or add zeros in the other? I tried to use the trunc with zeros on the ground, but it did not work...
  
  The following sql code:
  
  M06.mbr06_prv_id has no zeros, prv647.provider_id zeros. See bold below...
  
  SELECT
  M06.mbr06_prv_id,
  prv647.Site_ID
  Of
  Odw.mbr06_mbr_elig m06
  JOIN THE
  Odw.prv647_prov_exp prv647
  WE
  M06.mbr06_prv_id = prv647.provider_id
  WHERE
  M06.mbr06_subs_id = "999999999 '
  
  BTW, I have no control on how this data is represented in a table... !

  user12296489 wrote:

  Yes, this is how I see.
  LTRIM removes given characters from the beginning of a string. LPAD adds characters at the beginning of a string. I would use LTRIM in this case, because if you use LTRIM, you probably need to handle a single column. If you use LPAD, you have to play with the two columns, as one of them still has the extra 0, and it sometimes needs them.

  I tried to use the trunc with zeros on the ground, but it did not work...

  TRUNC is working on the kinds or DATEs; you have VARCHAR2s. You can convert them to numbers, but then you risk of errors to cause bad data (and it linked to the wrong data).

  If you are certain that m06.mbr06_prv_id never has extra characters, whereas the join condition can be

  ON   m06.mbr06_prv_id   = LTRIM ( prv647.provider_id
                                    , '0'
                         )
  

  If this isn't the case, CUT then the two columns.

  BTW, I have no control on how this data is represented in a table... !

  Report a bad design is for people who don't have not this control. Numbers are the number of columns, not VARCHAR2. If the ID really needs to be strings, they should be validated and standardized once, when they are placed in the table, no more, and more, in all queries that use these columns.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• How to validate two elements in a form that are not necessarily required

  I have a NO REQUIRED text field in which a user enters a value. I have a screen in the text field that will populate the result based on what is entered in the text field. I am wanting to validate the information entered in the text box.
  
  I added a validation indicating if the information exists, then display an error message. It works for the most part, but when the field is null, it gives me the error as well.
  
  How can I validate only if a value is inserted?

  Why are you trying to do this using a dynamic Action rather than standard treatment of page by page and branches?
