Array question

Hi guys,

I have a array where I put the products id and the amount of that same product in it.

example:

cart[23443] = 1; (where the array key is the id)

when I trace the cart array, flash walks trough all the keys (from 0 to 23443) and that takes a long time.

Is there a other way to do it? like this maybey:

cart[0][id] = 23443
cart[0][amount] = 1

thnx in advance!!!:beam:

PS: How can you trace the key of an array in AS?
