Hi, Any one help me. I am trying to implement a multistep form in the user registration process. but i unable to implement. Multistep form is not working in the hook_user case 'register'. 1. Call this multi-step form by a mere click of a link inside another form. 2. On submitting, this multi-step form should close and should take me back to the main form. 3. Also the main form should not refresh (i.e. all its values stay intact up to the time of clicking its link) Thanks. I am currently using SimpleTest to test a complex multi-step form implementation in Drupal 7. It made sense to do it this way as there are a lot of factors involved that all need to be accounted for and automating what form elements appeared on what page was the most robust solution.
