Unless you already have variables by those names stored in your session, 
you can add to the existing session without overwriting anything. You'll 
probably need to add a session_start() before setting the variables, then 
set them in the session rather than as globals. Then your ?page=error can 
do a session_start() and look for those variables in the session, and use 
them, delete them from the session, or whatever.
