thanks, ok, now if i have a session argument like this which registers a username sent from a form and searches a database for the usernames group it should all set right yes?

	   $query = "SELECT * FROM auth WHERE username = '$username'";
	   $result = mysql_query($query);
	   $row = mysql_fetch_array($result);
	   $group = $row[group];	   

   session_start();
   session_register('username');
   session_register('group');

it doesnt. am i doing something wrong? coz i cant see what.
