[development] How to pass form values to page that actually does something.

[Michael Prasuhn]

Add the display bits to your form builder function, and pass the data back with $form_state['storage'] or something like that. This is a basic multi-step form. There are a few examples in Drupal 6 core of this, or just google for "drupal 6 multistep form."
