Drop down boxes that add

[GrahamBB]

Hi

I am putting a form on my site.

I would like my drop down boxes to work like Excel. The user opens one drop down with price, then another with amount. I would them like the total to appear in another box.

You can find my test page at www.trophies-direct.co.uk/test.htm

You will see the grey column where I wish to the total to appear.

I would be grateful for any assistance.

Thank you.
Graham

you need to create a javascript function... trigger it on a onChange(); event

function AddCrap() {
crapTotal=document.formname.selecttrophy.value+document.formname.selectNumber.value;
document.formname.total.value=crapTotal;
}
