Java script to add vat /sales tax calculation

[aopps5@adobeforums.com]

Hi,
I have designed a form for contractor’s invoices and I would like some help with the java script to work out this calculation.

The calculation needs to times the stores value by the VAT rate % (sales tax)

i.e. 100 x 17.5% = 17.50

Can this be done and what is the custom calculation script?
Any help would be most welcome.

I can provide a copy of the form if required.

var a = this.getField("SubTtl");
var b = this.getField("Shipping");
var c = this.getField("Installation");
var d = this.getField("tax");
event.value = (a.value + b.value + c.value)* d.value;

I think this might be of assistance. I use this in a PO

Simple but it works

In the UK, certainly. It's a legal requirement to charge it.
