JavaScript Calculation Help!
Greetings! I have no experience with script, but trying to create a custom calculation script in my form to auto calculate QTY * Price Per Case = Extended Price for each row.

I found this formula on the Adobe Community, which works, but it also populates the Price Per Case and Extended Price from Row 1 on the rest of the rows. They should be blank until I fill in QTY and Price Per Case.
var firstValue = this.getField("Price Per CaseRow1").valueAsString;
var secondValue = this.getField("QTYRow1").valueAsString;
if (firstValue=="" || secondValue=="") event.value = "";
else event.value = Number(firstValue) * Number(secondValue);

Please help!
