dynamically populate a second page

Hi, I've read up on dynamically populating form data — and merge data — and it seems close to what I need to do not quite the right thing.

I'd like to have a two-step form submission process. On the first page, someone types in a Question on a form with one entry field. They click submit and are brought to a second page (form) with the same Question field (pre-populated with their first submission, and editable), plus new form fields for Name and Email. Clicking Submit on this page sends the form to the Notification addresses specified in settings.

Everything I've read seems geared towards dynamically populating a form from user data, not from a form submission. Am I on the right track? Can someone point me towards how to make this happen?

Thanks

Hi Rob, thanks for your reply. Forgive my ignorance — I can set the field to dynamically update — but how do I set the first form to do a redirect that passes the data via a query string?
Sorry for the newbie question, but your help is much appreciated.
Thanks

that's great; it works! Thank you so much!
