I have been working on a login script that will check a username and password against a MySQL database. I was using multi pages of html code and php code to handle this. I decided to look at functions() to help take away the repeated calls, but am running into problems on how to control them (I have included my script below). What I am trying to do is to have a login form appear once, the user signin, it check against database, and if unsuccessful replaces the $subtitle line in the ShowForm function with a message in the checknamepass function. When I run my code, it produes the login box, but seems to continue into the next function before waiting to get the submit. So when I try to run a loop with the FOR command, I get X copies of the login page, instead of one. Thanks in advance for the help... Tom
