storing checkbox data to DB

I read a great article here about storing checkbox data in a DB [also generating the form from the DB] http://phpbuilder.com/columns/laflamme20001016.php3?print_mode=1 I am having trouble getting the form to insert ... NOTHING shows up, well just HTML><HEAD></HEAD> etc. I have three tables: USER - CONST_SKILLS - LOOKUP_SKILLS You can view the source at the link above I am setting $uid to be "1234" [user 1234 is in the lookup skills table] $uid = "1234"; at the beginning of the insertskills.php I think that the script and theory are very good and could be very interesting, if anyone checks it out, maybe you can tell me why I have a Blank screen. thanks olinux ICQ me at 81933324 _________________________________________________________ Do You Yahoo!?
