can I just clarify, if there is already an exsisting session, why
doesn't the call to session_start() pick up on that fact and refuse to
create a new session.
php manual: "session_start() creates a session or resumes the current
one based on the current session id that's being passed via a request,
such as GET, POST, or a cookie"
It seems to me that was must be happening at the moment, for data to
be lost is that the variables are pushed to a completely new session
each time the form POSTs, this just seems to defeat the point of
sessions to me?
