How do I determine which text fields contain data?

Apr 29, 2012 4:46 PM

Although this is a sad testament to my programming skills, I have little shame since I only do this kind of thing perhaps once every two or three years.  I’m using FormCalc (mainly b/c I’m still learning Javascript and this form had already been written in FormCalc). 

 

Here is the problem:

 

I have three text fields (Textfield1, Textfield2, Textfield3). 

I created three variables (var1, var2, var3) and initialized them to 0.

 

In order to determine how many of the fields contain data, I used if/then/else statements:

 

if (Textfield1.rawValue == “”) then

     var1 =0

else

     var1=1

endif

 

Textfield2 and Textfield3 have similar statements (using variables var2 and var3 respectively).

 

To test the code, I have a message box returning the sum of var1 + var2 + var3.  With NOTHING entered into any of the text fields, I would expect it to return a sum of 0, but it returns a sum of 3!  If I enter data into just one or two of the fields, again it returns a value of 3!

 

I’ve tried initializing the value of the Textfields (Textfield1.rawValue=””), but I still keep getting a value of 3. 

 

It's probably a simple programming error, but again I'm not a developer.  Any help would be appreciated.

    I think you may need to change your code to: (replace the '' with null). Change from FormCalc to Javascript

     

    if (Textfield1.rawValue == null) then

         var1 =0

    else

         var1=1

    endif

    Just an FYI - you can mix and match FormCalc and JavaScript, even on the same object, just not on the same event.

     

    Many of my forms have both, FormCalc makes some things a lot easier to do.
