[development] Forms API

[Gordon Messmer]

I'm trying to write a new module, and having some trouble with the forms 
API.  I'm deploying this under Drupal 5.  I've been reading the 
tutorials and documentation for the forms API.  A lot of this module is 
cut and paste from the documentation.

I'm able to generate a form properly, and even theme it.  It displays 
properly in my browser.  However, when I submit the form, the _submit 
function isn't called.  The code is here:

http://phantom.dragonsdawn.net/~gordon/customerportal.module

The browser sends the form data via POST, and the web server responds 
with "200 OK", sending back the form HTML.  It doesn't log any errors. 
I have no idea how to go about debugging Drupal to determine why the 
_submit function isn't being called.  Can anyone give me some pointers?
