Javascript in a PDF Form

[movieking81]

I don't know if anyone here can help with this, but I have javascript issue in a PDF form. I have a field in the PDF form with a value of $12.00 (i.e. grandtotal). In another field in the form (i.e. Percentage) I'm trying to set the value at 80% of what the grandtotal value is. So, 80% of $12.00 is about 9.50, right? But all I get is a 0 total. The code behind the percentage field is below. Does anyone know why it doesn't work?

{
var a = this.getfield("grandtotal");
event.value = a / 0.80;
}
 

Thanks in advance

P.S. I using Acrobat 8 Professional

var a = this.getfield("grandtotal").value;
event.value = a / 0.8;


i am assuming a pdf form is the same as a normal form.. the trailing 0 on .8 isn't needed and .value on the getfield

Also, you need to multiply by 0.8 if you want 80% (but that's not a Javascript problem!)

Ha, yeah I meant multiple(*), honest. Thanks for the help, it works great.
