[item-list] is for looping the cart.
in your callback page, you just need an incrementing number which goes up to
the number of lines in the cart, right?
As has been said before, the WorldPay callback requests a page from IC in a
completely different session and so there are no items in _its_ cart.
Why don't you pass the number of lines in the cart to WorldPay and then use
this with the [loop] tag on your callback page?
