Percentage Calculations

hi,

for percentage calculations in pdf forms, you can use a custom javascript like: event.value = (this.getfield("field1").value / this.getfield("field2").value) * 100; but make sure to handle zeros to avoid errors. if you need to verify the math outside adobe, try this free online percentage calculator: https://fcalculator.com/percentage-calculator.html - it shows step-by-step and can help test your formulas quickly.

hope that helps!

This can be done with a simple script, but I would recommend you rename your fields to something a bit more consistent.

For example, if you renamed them to Number1, Number2, down to Number15, and Perc1, Perc2, etc., then you could use this code as the custom calculation script of the Perc1 script:

var total = 0;
for (var i=1; i<=15; i++) {
    total+=Number(this.getField("Number"+i).valueAsString);
}
it (total==0) event.value = "";
else event.value = Number(this.getField("Number1").valueAsString)/total;

This code can be extrapolated into a more generic function and then called from each of the Perc fields, instead of copying and pasting it (and changing the name of the field in the last line), but that's the basic way of doing it.
