I'm having trouble with the html.pl file.

I started off by installing the dbman demo, everything was fine. Next I modified the .cfg file to match my new database and fields. Everything worked fine with the demo's html.pl (obviously the disply was not correct because I had switched to another database but the forms displayed fine). Additionally if I set the auto generate html on the script will work fine but I want control over the display. I modified the html.pl file, made sure it was ascii with a 644 permission. When I launch the scrip using the new html.pl file I get the infamous internal error. I've checked my fields in the html.pl file but I can't see what I have done wrong. I've put my database, .cfg and html.pl files to the following address as text files

Any help is greatly appreciated, thanks in advance
