What you're actually doing is registering a variable that doesn't exist until after it's been registered. To fix simply swap lines and set your varaible before you register it in the session.. session_start(); $auth = "yes" session_register("auth"); However I recommend anyone working with sessions to use the $_SESSION super global array rather than the session functions. It's more direct and alot more intuitive since you're not creating two instances of the variable.. session_start(); $_SESSION['auth'] = "yes"; HTH, Kevin
