Can't get _submit to fire in my administration page

I'm completely stumped by what's going on here. I have a very simple module that absolutely will NOT update the admin page. If I put the update commands (variable_set()) into the _validate function it works fine. If i put it into the _submit function I get nothing. It's like the _submit function doesn't even get called like http://api.drupal.org/api/drupal/developer--topics--forms_api.html/6 says it should. The module tutorial (http://drupal.org/node/206761) has little to nothing to explain what to do after the validation step. Anyone care to offer some insight into why this doesn't work?
