Everything is fine , ive asked a coder and they cant figure it out either.

if everything were "fine", you wouldn't have a problem now, would you.

seems the session isn't being started.

try chainging your short tag to a full tag:

<?php
session_start();
//...rest of code...
?>

instead of:

<? session_start();
