the manual says ( http://hu.php.net/manual/en/ref.session.php )
"If register_globals is enabled, then the global variables and the
$_SESSION entries will automatically reference the same values which
were registered in the prior session instance. However, if the variable
is registered by $_SESSION then the global variable is available since
the next request."

that's why it is the same
I think you should read the value from $_POST and put it into $_SESSION
to change it

hope that helps
