Desperate for help: ADDT registration form

New to ADTT and back again with another, more urgent problem.

I have used ADDT to create a registration page, using UPDATE instead of INSERT (this is necessary because the users are already in our system as contacts).  To accomplish this I had to do some hand coding and I fear I may have gone awry.  Initially I kept getting a blank page with the message "error: internal server" message when the page loaded...currently I get "Fatal error: Call to a member function addField() on a non-object in /home/agciorg/public_html/events/2009/259/users_Registration.php on line 33."  Now I can no longer open the registration page in Dreamweaver -- freezes DW everytime.  So I'm trying to edit in Text Edit to get it back to a functioning page.  I've already rebuilt the page from scratch twice trying to get things to work and I'm on a major time crunch and just can't afford to do it again.  Below is the current code (I've also attached the php file as a .txt)...any help in resolving my issue would be much, MUCH appreciated!
