Text Field Calculations

Yes, you can use substrigs to compare each letter of each string. The exact syntax will depend upon if the form is an Acrobat Form or LiveCycle Designer form and if LiveCycle Designer which scripting language.

I am using an ADOBE Acrobat Form. And am trying to subtract two fields, "Total Assets" from "Total Liabilities."

You need to set the format for the fields to "Number"

And then for "Total Equity" field you can use the following "Custom calculation script":

event.value = this.getField("Total Assets").value - this.getField("Total Liabilities").value;

There are a number of eSeminars on demand and articles about using Acrobat Forms and JavaScript that can help you learn how to perform various tasks in JavaScript.

So I'm assuming that if I had multiple text fileds that I wanted to subtract from one field in particular the formula would be:

event.value = this.getField("I").value - this.getField("J").value- this.getField("K").value- this.getField("L").value- this.getField("0").value;
