Help From David Powers Please

David,

I am using the redirect to a personal page from page 515 of The Essential Guide to DWCS3 in the following form: $_SESSION[MM_Username].php in the "if login succeeds" field.

This does not work for me the first time the login page loads. I get a 404 error. However, it I hit the back button and try it again it works. I have a guess that the Session variable is being set before it pulls the Username from the DB, but I don't know enough to be sure. I tried moving the variable assignment lines around and screwed it up royally.

This is being run on a live server. Listed below is my code that works if I hit the back button. Any help would be greatly appreciated.

Thanks.

Glenn
