    How do you add some values if the field is empty?

    niicoleloor Level 1

      I am not familiar with Acrobat language. I'm trying to create a form fill with the W4 Form. There's a field where I have to add lines 3 and 4, but you can include amounts for credits from another worksheet. So I'm trying to sum the field 3 and 4 if the event value is empty, but if there're some other amount I want to add then I could add the manually and type them in the formfill.

       

      This is the code I currently have:

       

      var v1 = getField("W4D3").value;

      var v2 = getField("W4D4").value;

       

      // Set this field value equal to the difference if the field if empty

      If (event.value == null)

      {

      event.value = v1 + v2;

      }

       

      PLEASE HELP!
