I'll attach some simple shopping cart / update code here. You can adapt it to your
needs.

<h3>Cart</h3>
<cfif get_cart_lineitems.recordcount eq 0>
<cfoutput>
There are no items in your cart. <cfif session.loggedin neq 1>If you think
there should be items in your cart, try <a

in</a>.</cfif>
</cfoutput>
<cfelse>
Note: You can remove a product by updating its quantity to zero and updating the cart.

This is not my inventory, it is their inventory. There may be multiple
locations entering in their own inventory. (Think more along the lines of
an office inventory rather than a store inventory).
>I wouldn't recommend CFGRID or CFFORM. Those are limited functions.
Ok, alternatives?

Array type? Remember, I am somewhat new to this part of it.
