Your post caused me to go test our theories...
In general you are correct.
A simple array is faster than a simple list. If you start getting into
arrays of structs or multi-dimensional arrays then lists can be faster, but
ONLY if you DON'T use the listAppend() function (built the list by saying
tempList = tempList & "whatever")
An old application I wrote years ago ran very slow with arrays of structs
and I was able to cut the processing time by a factor of 10 just by
switching to lists, but I suppose that would be an extreme case.
Just goes to show we should never stop questioning ourselves!

Subject: RE: Deleting Row from Array
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)>

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.
