[development] editing form and submitting values to database in custom module not working

[Randy Fay]

I encourage you to start with a working example and build from there. There
are several examples in the Form Example in Examples project (
http://drupal.org/project/examples), and there are examples throughout core
that you can look at.

In addition, focus on learning how to debug so you can solve these yourself.
http://randyfay.com/debugging_drupal may be useful to you, and the Devel
module with its dsm() function is widely used by people to figure out what's
going on in situations like this.

This is a very helpful group, but they won't (usually) help you debug your
code or learn the basics of Drupal development.
