thanks for your reply.

I've re-looked through the uc_cart.module and the bit I need to theme lies under uc_cart_view_table($op, &$form). I've stuck a phptemplate_ in front of the function name but you won't be surprised to hear that didn't work.

Is this function simply out of bounds? I've got the same problem with the function uc_cart_add_item()

Thanks,
Marc
