I'm fairly certain that arrays are much, much faster than lists. Lis
ts are
nothing but strings, and I can't see how looking for a user defined
delimiter character in a list could be faster than a system defined
delimiter in an array.

In CF lists are much faster than arrays. You can access itemID and q
ty
by
using listFirst() and listLast(). Besides, it's easier to understand
and
manipulate single dimension arrays.
Anyway, that being said, here is your problem:
arrayDeleteAt returns a boolean true/false, so when you say
<cfset session.cart = ArrayDeleteAt(session.cart,form.counter)>
you are actually setting session.cart to "true". Do this:
<cfset temp = ArrayDeleteAt(session.cart,form.counter)>

Subject: Re: Deleting Row from Array
It's two dimensional because I'm storing item ids and quantities, so
[1][1] is an id and [1][2] is a quantity etc.
With your code I'm getting:
ArrayDeleteAt(Array, Position): Cannot delete element at position 3.
The
array has only 2 elements.
And the Array has three elements.
