Peter, thanks for your help. I did a bit of work on my own and came up with this using an OnChange and pull down menus:
function maketotal() {
var itemA=document.bulb.A.value * 25;
var itemB=document.bulb.B.value * 8;
var itemC=document.bulb.C.value * 8;
var totalcost= itemA + itemB +itemC
document.bulb.TOTAL.value=totalcost;
}
How would I use a loop in a case like this?
For each item in document.bulb ??
//do stuff
Next
If I am setting the values, do I "need" to use the ParseInt and ParseFloat? What kinds of things happen when I don't use them?
TIA

Jason,
If you want to update in real time, just slap an onChange event handler
on all changeable text fields. Remember to parseInt() or parseFloat() the
form field value since it starts as a string; not much more to it. It's
even simpler for checkbox values, as you can see at
http://www.digitaltechnologyconsulting.com/orderform.asp .
Cheers,
Peter
