I am trying to have a form NOT prefill. I had it working when I tested it, but now that I have sent out the email it appears to have reverted back to prefilling.
What I've done (and confirmed is still the case) - in the landing page, selected Landing Page Actions->Edit Form Settings -> DEselected the Prefill box (i.e. no check mark).
Why is my form still showing as filled? I am trying to get people registered for a webinar and due to the WebEx integration, need them to complete the form each time.
