I have been using Acrobat Adobe for a while now and have been able to do basic calculations. I have not worked with the "Custom calculation script" and was wondering if someone can help me with the calculation, if there is one.

I am wondering if there's a calculation for my statement below:

If "A" has a dollar amount and B is blank, answer is A;

If  both "A" and "B" have dollar amounts, fill answer with B.

Your help is greatly appreciated.

Assuming that you have three form fields named A, B, and Total, you can use a custom calculating script as shown   below for the Total field:

var a = this.getField("A").value;
var b = this.getField("B").value;

if (a && b !="") event.value = b;
if ( (a !="") && (b =="") ) event.value = a;

else event.value ="";

If is best to write one of selection statements as mutually exclusive.

var a = this.getField("A").value;
var b = this.getField("B").value;

if ((a != "") && (b !="")) event.value = b;
else if ( (a !="") && (b =="") ) event.value = a;
else event.value ="";
