Hi Philip, You'll probably want to move your session handling code to the top of the main entry point of your application, rather than starting it in a sub-page. This way all subpages get the benefit of being able to use the session data. Even if not strictly necessary, the option is there in the event you add features later on that require sessions throughout the application. A possible alternative is to use output buffering, which allows you to start a session even after output has been sent. Though this is more likely a kludge rather than a good solution to the problem.
