OK, I made the above change to the login.php page and it is working - when I go to update_self.php, it is now populated with my data. I made some changes as a test and hit the Save Changes button, and again I am faced with the dreaded blank page. The Update Record Server Behavior is set to Current Page Submit, and after updating it should go to thankyou_update.php. Is the current page submit incorrect? The two files are attached.
