Module development and code questions

I am attempting to write a module that makes use of the forms api I currently have it tossed up on paste bin, but I'll add it here too...

The problem that I am running into comes when I hit the submit button for the form. I get a blank white screen and no results inserted into the db. I've spent the last couple of hours searching the handbook/forums for a solution and I just can't seem to figure this out... a trip to the irc dev channel didn't resolve it either...

If anyone has any insight that can get this resolved so I can move forward I would greatly appreciate it.

I hope this is the right place to post this.
I have been working back and forth with nevets over in the post installation support forum to develop a function to be used as a module to check titles and fields in custom content types when nodes are created. You can see the thread at http://drupal.org/node/89599. Unfortunately, I've been cluttering-up the thread over there with my posts so I figured I had better start my own thread to keep things more organized.

nevets had written a nice little function that checked for duplicate titles for nodes of a specific type. I wanted to do a more robust version, and he really helped me out in with my issues (I'm really new to PHP). I'm calling the new function "Dupe-R-Scooper" since it tries to scoop-up duplicate data before it gets published.

Anyway, long story short, I'd like to get a little help with the function, and get this developed into a full module with an admin-area UI.

The basic overview of the function is this:
1) we hook nodeAPI to catch the validate operation
2) we use a switch to check a number of node types
3) we run a query to pull specified fields and node title/nid from the {node} and {content_type_*} tables.
*3b) I need to somehow write a loop here to make sure we check everything that could be a match (but don't know how).
4) we run a few if() conditions against the new and existing data

i 'd like to use php file get some msg then use simplnews ' api to send it to all subscribers.

does any knows about this ?
