When I added the die code and saved the file, the Server Behavior changed as you noted. I had used the WebAssist Wizard/DataAssist but it only allowed me to work with one table (kids) and the loged in userID and pw are in another table (parents). I have gone back to the previous page version before the added die code.
I am sure that you are correct regarding the session variables. To start/continue the session on the member_Registration, do I need to add the block code to start (continue) the session? Do I need to set parents session varibles somehow on the previous webpage (parents_Profile) so that they can be carried forward and referanced on the Member_Registration page?
How do I confirm that the session variables are stored and what their names? How do I update it to look in the $_SESSION instead of the $_POST? Do I put it in the start session block at the begining of the page? What is the correct syntex? Examples that I have read on the web seem conflicting and what I have tried does not work. I have spent days on this and am totaly lost. Once I have a good example that can work, then I will be able to understand and reuse the same principle as needed.
