You must use session_start() on every page with sessions because session_register() won't work with the associative arrays. 2. Every reference to session_register must come out and replaced with the code to set the session var $_SESSION[]. These two actions are probably at different places in the script, so remove the reference to session_start, and at: 3. Every reference in every script to a global session var will need to be replaced with a reference to $_SESSION['rcity']; 4. You'll also need to change any references to session session_unregister to unset($_SESSION['rcity']). Read the notes in the manual, as you can't mix the use of $_SESSION and session_register(), session_unset(), etc. If you use the arrays, everything must be done with the arrays. I'd suspect the reference to undefined function is caused by a typo and placing a $ in front of a function name such as $session_start().
