Conditional fee calculation in document level javascript

Question

Hi, I'm trying to create a document-level javascript to calculate three fields with conditions. The three fields are "LicenseFee", "ServiceFee", and "Total". The "LicenseFee" is the only one not read-only; the other two fields will autocalculate based on the number entered in "LicenseFee".

I'd like the behavior to go as follows: when "LicenseFee" is empty, "ServiceFee" and "Total" are also empty. When an integer is entered in "LicenseFee" (for example, 120.00), "ServiceFee" will multiply that number by .025 and add 2.00. "Total" will then add "LicenseFee" + "ServiceFee".

This what I have so far - up front I am a novice to javascript&colon;

function FeeCalc()

{

var Licensefee = this.getField("LicenseFee").value

var ServiceFee = this.getField("ServiceFee").value

var Total = this.getField("Total").value

if (LicenseFee='') {

Service='';

Total='';

}

else

{

ServiceFee=(LicenseFee * .025) + (2.00);

Total=LicenseFee + ServiceFee;

}

I appreciate any and all assistance! Thanks so much! Bill

Place it as the custom calculation script of a (hidden) text field.That worked! Thank you so much for your help!

In addition to the correct remarks above, be aware that your code doesn't actually change the value of any field.

To do so you have to apply the variable directly to the value property of the fields at the end of it, like this:

this.getField("ServiceFee").value = ServiceFee;

this.getField("Total").value = Total;
