Okay, obviously I'm being especially slow today, b/c I'm still not getting
this. Here's what I've got.
<script LANGUAGE="JavaScript">
function Countit() {
cost=0
for(i=0; i<=16; i++)
{
zip = "zip" + i;
if(document.memberform.zip[i] = "")
{
//this is for empty boxes
}
cost = cost + 1
document.memberform.amountdue = (cost * 79.95)
return
}
}
</script>
and then there's the text boxes
<input type="text" name="zip1" size="6" onchange="CountIt()">
<input type="text" name="zip2" size="6" onchange="CountIt()">
<input type="text" name="zip3" size="6" onchange="CountIt()">
plus 12 more. And then there's the amount box.
<input type="text" name="amountdue" size="20">
Right now when I try this, the page throws an error saying "object expected"
and give the line number of whatever textbox I just typed in. All I'm
trying to do is have it update the amountdue box.
TIA,
