here's one

...okay folx, this one seems pretty straightforward and easy, but I haven't found a solution that works for me...

Basically, I've used javascript to calculate an amount on my webpage...but haven't been successful at passing that return to the "amount" hidden input for a shopping cart. So I've got:

<input type="hidden" name="amount" value=amount()>

function amount() {
amountadded; return;
}


Doesn't seem to work for me. Any suggestions?

you can not assign value to a textfield like that, here is the possible answer

document.formName.hiddenFieldName.value=GetTotalValue();

and make sure that you trigger some event that will cuase the above line of code to be executed.

...tried that earlier, Khalid, but no dice. But it makes me think (I'm thinking about PayPal here now, and what their server expects)... originally the value is assigned, say..."20.00." It's a number, but in quotes like text. Would I have to convert a number return from a function to make it palletable for their server? How might I do that?

Also, I've seen you post a link here once to some guy on AOL that had a demo on calculating for PayPal, and if you could include that here I might be able to find out how he passes his value.

Thanks. okham
