Re: [development] $form_state passed to form function from drupal_get_form()

I haven't seen anything written in PDD or online that indicates that I have to have $form_state as the first parameter in my form function definition when I want to pass it a variable. Am I missing something? From http://api.drupal.org/api/drupal/developer--topics--forms_api.html/6 'Note that the form builder function always takes $form_state as its first argument'
