Hi 🙂
@ genius: Then dont read this page. Arrogance is the last thing we need.
I am quite new to this as well but the following came into my mind:
Did you try to assign a value to the variable AFTER you registered it? And another thing (dont be mad if it isnt true, it is just a presumption), dont you have to pass the session_id between the files in order to know which set of variables belongs to which user?
I hope some of these n00bideas help 🙂
