Hi,
 
Beginner Question here..
 
I have 2 fields, 1 for subtotal and 1 for extra charges, I want to sum these 2 fields and get the sales tax of 8.25% into a 3rd field. I have searched everywhere and I only found the way to do it from 1 field.
 
Thanks in advance for your help.

Hey,

Thanks for the tip.

It is now in my ebookshelf now.

However when I select the tax field and do the following:

var f = this.getField("Sub T","extra");
event.value = Math.round(f.value * 7.25) / 100;

it gives me a wrong calculation, looks like it is only calculating the "Sub T" field and bypassing the "extra" one.

Thanks again in advance for your help.

Gvilla.

Hell-o!
