function workbench_email_notification_validate in Workbench Email 7.3

Validates the options chosen.

Users can go back and forth between fieldsets causing the email options of a previous Workbench Access section displayed and chosen when the user actually went back and changed there initial decision. Instead of trying to do something fancy with dom and JS, I chose to validate in PHP and throw an error.

Parameters

array $form: The form array.

array $form_state: The form_state array.
