Java to add two fields, use total with Paypal

I know it's simple, but all resources more complicated things and I can't understand it.  How can I add several fields numbers, user entered (ID 'Number 1', 'Number2') in real time to calculate a total displayed in another area.  And the total number or text field?

Second part of the question is I added a PayPal button down which will understand through Paypal, but it will not fix the price is I want PayPal to take the price of the total. How could I get this?

#1 JAVA (Oracle) is not the same as JavaScript.  They are 2 very different programming languages.

Here is an example of summation of the fields with values defined using jQuery

#2 that it will depend on the PayPal account type you have.  Here are the basics for PP Standard payments.

  • Add two fields of char

    Hello..

    I have a form with three fields with any type of char with length 5 data. I want to add Field1 and Field2 and save the result in field3.
    Data in Field1 and Field2, time in char format. I want to add these two fields and save the result in field3 as tank.
    But the addition of these two fields should be similar to the addition of two time values.

    Ex:
    Field1 = 04:30 and 05:30 = field2
    where in Field1 * 04 * refers to the hours * 24 HR format * and * 30 * refers to the minutes.



    Thank you..

    Try this

    :filed_3:=LTRIM(TO_CHAR(TO_NUMBER(SUBSTR(:FILED_1,1,2)+SUBSTR(:FILED_2,1,2))+TRUNC(TO_NUMBER(SUBSTR(:FILED_1,4,5)+SUBSTR(:FILED_2,4,5))/60),'00'))||
    ':'||LTRIM(TO_CHAR(MOD(TO_NUMBER(SUBSTR(:FILED_1,4,5)+SUBSTR(:FILED_2,4,5)),60),'00'))

  • Add two fields

    I have two fields in the query that are created by a case statement. I created a calculated field in my report: Data Type Float, calculation: nothing, perform the calculation on: query. Tuition + query. RoomBoard, first value query. Tuition + query. RoomBoard, reset the field when: evolution, the Reset group: ID

    I get the following error when I run the report: query. Tuition + query. RoomBoard is not a valid expression of ColdFusion.

    What I am doing wrong?

    It appears that you want this amount for each record, right?

    If this is the case, then you may not use a calculated field. Insert a field in your detail band, choose "expression entered manually" and then use "question. Tuition + query. RoomBoard' as the expression.

    See you soon

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

    All,

  • Simulating a "Required" conditional on two fields using the field Validation

    I'm trying to 'require' users to fill in the Email address field or the primary phone when you create a Contact record. I had an idea of how do, but couldn't make it work. Any suggestions?

    Thanks in advance,
    Charley


    I working on the screenplay of is as follows:
    The customer wants to check on two fields on a contact record - the main phone and primary e-mail address fields. The envy of their users must complete one or other fields. This kind of conditional required parameters being out of reach for the workflow, I tried to get validation in the field to work. I tried to implement something like the following as the validation rule:
    [example as WorkPhone <>] is Null AND that [< ContactEmail >] is Null
    Then a validation message is displayed informing the user that one or the other needs remaining.

  • Formula: Add two fields and divide a

    Help!


    I'm figuring a field that requires information of 2 other fields. I need of field "STR_2" to calculate the sum of the 'STR_1' field and 1/2 of the field 'Level' (rounded down). I use the following formula in the field "Calculate Custom script":

    {If (this.getField("Level").value! == {this.getField("Level").defaultValue)}

    Event.Value = (Math.round ((this.getField("Level").value - 1) / 2) + (this.getField ("STR_1")));

    }

    else {}

    Event.target.defaultValue = Event.Value;

    }

    However, it keeps returning the value "0 [ObjectField]" when the value of the 'level' is 1 and 'STR_1' 2 (it should return a value of '2').

    When I use the following formula:

    {If (this.getField("Level").value! == {this.getField("Level").defaultValue)}

    Event.Value = (Math.round ((this.getField("Level").value - 1) / 2));

    }

    else {}

    Event.target.defaultValue = Event.Value;

    }

    It works very well, and I get a value of '0' (1/2 "Level" rounded down). So, how can I fix this so that I get the right calculation?

    Thanks in advance!

    (If that makes a difference, I use Acrobat Pro XI on a Windows 7 laptop).

    You should correct this line in your first script for:

    Event.Value = Math.round ((this.getField("Level").value - 1) / 2) + + this.getField ("STR_1") .value;

    But this calculation does not do what you say you want. It subtracts 1 to the value of the field level and divides the result in two and adds the value of STR_1, which is different from what you have described.

  • How can I add a field number of the apartment to the House address Web Forms?

    The home address is the only area that is included with the standard format of the web Contacts. How is I can't add a street address, apartment/Suite without creating a custom field for this?

    There is currently no way to include a second address field from House to apartment numbers or after which CRM are related. You must create an entire custom form for this.

    I created a work around for this.

    (1) expand the CRM database and add two fields called, 'Address' and another called ' apartment/Suite '.

    (2) add these new fields to the contact form

    (3) use jQuery to collect and store the values

    (4) concatenate values in the HomeAddress field using jQuery

    $('#StreetAddress,_#AptSuite,).bind ('keypress blur', function() {})

    $('#HomeAddress').val ($('#StreetAddress').val () + ' ' +)
    $('#AptSuite').val ());
    });

  • dynamic field using Add field parameter section

    Hi all

    I think I missed something in how to add the field section objects and help will be appreciated.

    Your syntax 'add the field heading' is incorrect.

    You used the name of section rather than the name of the section group:

    ALTER INDEX test_field_ox PARAMETERS ('Add SECTION TEST_FIELD_SG TAG A2 VISIBLE FIELD');

    In fact, you could run the query in the form:

    SELECT COUNT (*) FROM test_field WHERE (content, 'iacob in TEST_FIELD_SG') > 0

    and this would have worked, but what you really wanted to do was:

    ALTER INDEX test_field_ox PARAMETERS ('Add SECTION A2 A2 VISIBLE TAG FIELD');

    Do not forget that a section name (what you are looking for breast) is not necessarily the same as the section tag (characters inside <> and) and also the names of this preference, the section names, etc. are never stored in the index - only parameters of these preferences and sections are stored internally. When you understand that, you will see that it is senseless to provide a section group name in an ALTER INDEX operation.

  • Compare two numbers using java

    Hello, pls help.

    I have brought three named 'field1', 'Field2' and "field3".

    And the user will be key in a number of 'Field1' and after the key of the user in another number in 'Field2 '.

    The number will be automatically the number of "field1".

    If the 'field1' > 'Field2', the system displays an alert saying 'Field2' must not be less than "field1".

    If the 'Field2' = < 'Field2', the system will run an equation as "field1/field2*100%" and put this percentage lead in "field3".

    Can someone help me with the code please...

    Thank you

    The way I want to do this kind of things is by first creating a feature in your document level scripts.

    The function would look like this;

    function addFields() {
         var fldT1 = this.getField("Field1").value;
         var fldT2 = this.getField("Field2").value;
         var fldT3 = this.getField("Field3");
    
    if (fldT1 > fldT2) {
         app.alert("Field 1 is greater than Field 2");
    }
    else if (fldT1 < fldT2) {
         fldT3.value = fldT1/fldT2*100+"%";
    }
    else {
         fldT3.value = fldT1/fldT2*100+"%";
    }
    }
    

    Then I call this function in two fields 1 & 2;

    Action: Blur on > execute a JavaScript script

    addFields();
    

    I also make sure that the format of fields 1 & 2 are on number so that the other user cannot add a letter or character not number in the field.

    Right click on the field > properties > Format > number

    Check all of the fields that you don't want other users to be able to edit/change read only and you should be ok.

    Hope this helps,
