Without seeing the entire script, would this change help?

Change:

PHP Code:

session_start();

if (!isset($HTTP_SESSION_VARS['first_name']) || $HTTP_SESSION_VARS['first_name'] != "first_name") {

header ("Location: /members/login_form.html");

} 

To:

PHP Code:

session_start();

if (!isset($HTTP_SESSION_VARS['first_name']) || $HTTP_SESSION_VARS['first_name'] != $first_name) {

header ("Location: /members/login_form.html");

} 

Just a shot in the dark.
