All the functions work properly, let's go through it step by step. page1: session_unset("IDmember"); Firstly, session_unset() does not take parameters, it simply clears all the session variables. Secondly, I suspect what is happening here is that your session is not started at all on page1 since you didn't call session_start() or have session.auto_start = 1. Now, on page2, you have session_register() which automatically starts the session and your value for IDmember comes back and then saved back out to disk after script finishes running. -Andrei * I don't mind going nowhere as long as it's an interesting path. *
