Because the session is not being started on the second page. to be able to
get the contents of a variable that is in a session environment, you must
first initiate sessions with the call session_start(); even if that is all
you do before referancing the varialble.
so, add session_start(); just after entering the second script and is should
work. if it doesn't, if you have php 4.1.0 or newer use $_SESSION['course']
if older version you are working with, use $HTTP_SESSION_VARS['course'] .
Hope this helps.
