Java or Validation script that will give a negative result no matter if the number entered..

Hello,

 

Can anyone offer any suggestions on how to write a Java or Validation script so the result is always a negative number?  The PDF I'm working on has a field (which is named l6) that is a field that one can enter a number.  I'd like the number to always be a negative, so if one enters 3,000 then when they hit enter I'd like the number to be -3,000.  If they enter -3,000 then I'd like the number to be -3,000 for the field (l6) that they are entering the number for.  I feel like a validation script is the way to go with this but honestly i have no idea.  Thank you in advance for any input

    Use this script.

     

    if(event.value > 0) event.value = -event.value;

    I used if(event.value > 0) event.value = -event.value; to make the row for the "Less: (Advance)" always a negative number. 

    The row below it, is the totals, so in Adobe, i created the calculation formula to be a the sum of everything on that column (which would really subtract the "Less: (Advance)" ). 

     

    When I do "preview" in Adobe, all the validations and calculations work.


    When I save the file as a PDF into my computer, and when I try to fill out that file from the hard drive, the calculation adds the  "Less: (Advance)" row instead of it treating it as a negative number.  How can I get it to work?

    Do you use Acrobat to fill form?

    Did you use a calculation script to calculate the total?
