1. Are you 100% sure register_globals is turned on?
2. You session_register your variable before you change it. Replace
$ShoppingCart with $_SESSION[ShoppingCart] every time you use it. This way
you are modifying the session variable actually in the session, not just
the one time.
session_register() copies the named variable into the session space, but
adding or removing items from that variable does NOT change it in the
session if you use _register. If you modify $_SESSION[shoppingcart]
every time, then you are actually reading/writing to the real session
variable and don't have to worry about it.
