Ok, so you have this:
items[1][1] = itemID1
items[1][2] = qty1
items[2][1] = itemID2
items[2][2] = qty2
items[3][1] = itemID3
items[3][2] = qty3
In this case my previous assumption would be wrong and the error you
get
using my code is understandable.
FYI: you'd be MUCH better off storing them in a single array and
seperating
them with something (an underscore maybe) like so:
items[1] = itemID1_qty1
items[2] = itemID2_qty2
items[3] = itemID3_qty3
In CF lists are much faster than arrays. You can access itemID and qty
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.
