A) PHP variable names are case-sensitive, $_SESSION != $_Session
B) You probably want to replace the () with [].

You cannot (should not) mix the use of $_SESSION with session_register().
RTFM.
If you redirect without closing the session then any changes to the session
variables will lost. So you need a session_write_close().

Use:
isset($_SESSION['qs'])
or
!empty($_SESSION['qs'])
rather than
$_Session("qs") != ""
and similarly for $_SERVER['QUERY_STRING'].
