I think my title says it all.
I want a lightbox form (that communicates via ajax?).
That has a progress bar (updating after each portion is submitted).
At the end (last portion of form), off we go to PayPal.
After successful Paypal back to site where GF creates a subscription (or user account or membership, whatever GF does).
The subscription can be behind the scenes.
After subscription, off to the print/download page (Gravity Forms PDF Extended).
Is this easy as pie?
