Note Submitter: pscsuk at NOSPAM dot gmail dot com ---- Remember that 'globalizing' $_SESSION like this only does half the job. It makes "read-only" globals. Any changes you make don't get written back to $_SESSION when the script ends. You either have to do that manually, or, instead do something like: $MyVar = &$_SESSION['MyVar']; This makes $MyVar into a reference for $_SESSION['MyVar'], so, every time you change $MyVar, it really changes the value in $_SESSION - thus, at the end of the script, when $_SESSION gets saved, your changes get saved as well.
