adding percentage to calculated form
<p>hope someone here can help. I need a form javascript that auto calculates totals. I have been messing around with a form script I downloaded (hats off to Paul McFedries) The totals are working fine but I need it to also calculate tax (at 10%) and add that to a sub total. I have the basic form working here:

<p>I'm a complete javascript beginner and don't have a clue where to begin. Can anyone help or show me the way?</p>
