Positive Values

In your calculation script, include an 'if' statement to change the result of the calculation to zero. The 'if' statement is described in the "Scripting Reference" under the 'Help' menu.

I use already use it. I type in calculate event but it didn't work. I'll test more times and look what's problem!

thank you...

I can not see the code.

Have you looked at the JavaScirpt console to see if there are any errors?

var MyAns = 0;
// perform the calculation and put the answer in the MyAns variable

// test for a less than zero result
if(MyAns < 0) then
// force result to zero
MyAns = 0
endif
// insert result into field.
MyAns

The code is like you post, it's because i think so it's strange... by logic this should worked!!

Again, have you looked at the JavaScript console to see if there are any errors?

The Acrobat JavaScript Console (Your best friend for developing Acrobat JavaScript) by Thom ParkerThe code is like you post, it's because i think so it's strange... by logic this should worked!!Like is similar to close. And close only counts in horseshoes and hand grenades. You may also need to check your form field calculation order.

how i do that (JavaScript Console )... but i use FormCalc language!
