Well, I figured it out. Thank you for all the replys. What i needed to
do is add a hidden field to the form and then just manipulate the
information passed through that. I'm making a shopping cart. I was
trying to dynamically update the qty value if a user clicked +/-. I
was having a hard time trying to find out how to +/- the qty's while
at the same time updateing the totals. a few lines of code did the
trick...
<cfif IsDefined("form.add_to_qty")>
<cfset session.cart[#prodID#].quantity=session.cart[#form.prodID#].quantity+1>
<cfelseif IsDefined("form.take_away_from_qty")>
<cfset session.cart[#prodID#].quantity=session.cart[#form.prodID#].quantity-1>
</cfif>
Actually, cfset session.cart[#prodID#] was a typo. I was going to put
form.prodID but when i did that earlier it was +/- 2 instead of one
because i was inside a loop.
I'm not sure if any of this makes sense but that was my solution.
Thanks again for the help. It really helped when it was pointed out
that only 1 form gets processed.
