Hi I have a several php files which actually is a registration form with validation. So if someone fills up the form correctly, the values will be stored into database. When I am running the file, the form field displays but it has no functionality. I don't know exactly what is the mistake I have made?

The web url is the following if you would like to have a look: http://bphf2012.org/index.php?option=com_jumi&fileid=11

The files can be seen from here: https://www.dropbox.com/sh/vof0p4heo4csdn9/dj2NfgcWuE

Thanks.

After fixing the error, the reason why the functionality isn't working because on the form action location, I have put just register.php. I didn't realize that I have made that silly mistake..
