OK, I've gotten everything to run except the creat_users.php when the restict access block is added. I'm using the code I downloaded from this site, changed the MySQL info for my server and when I login and try to go to the create_users.php it sends me back to the menu.php page. I'm not sure where the error is.
This is the code block :
<?php
    session_start();
    // Check the Users status, if not Admin level
    // redirect back to the menu.php page
    if($HTTP_SESSION_VARS["statusCheck"] != "Admin")
        header("Location: menu.php");
?>

and here is the code block that creates the session on the login page.

<?php
    // This section is only run when the form has been submitted
    if($HTTP_POST_VARS['Submit']=="Login"){
        session_start();
        // Check whether the login details are correct, and put
        // the user status into a session variable.
        $statusCheck = check_login($HTTP_POST_VARS);
        if ($statusCheck == "Admin" || $statusCheck == "Staff"){
            session_register("statusCheck");
            header("Location: menu.php");
            }
    }
?>
thanks. Liked the book by the way.
