edit wrapped the code tags around the code

Now that is chat.php, There are other files.. Refresh.php, Chatroom.php + Submit.php

All of this is online.. And on my server.. It works.. Directly from the database.. But not from Chatroom.php ..

If you want the code posting for those also.. Please ask.

Thanks

Scott
