Yes. print_r($_SESSION); to check what your session actually holds.
Be warned that session_start() has to be declared BEFORE any output, or it
won't work. So not in 'the centre' of your page, but as one of the first
things 'on top'. Even sending out a simple space or line-break before
session_start() will render it useless.
Another word of advice: don't rely on shorttags: always use <?php instead
of <?
