It's optional; do you have the "register_long_arrays" option turned on? I
believe it's off by default in PHP5, so only the superglobals ($_GET etc.) will
hold values, and not the old $HTTP_GET_VARS globals.

It's a bit weird to use both $_GET and $HTTP_GET_VARS at the same time - you
probably ought to just use $_GET throughout - after all, they contain the same
data.
