Cornerstone Forms - newbie issues

I’m using Cornerstone forms for the first time on a new project. I’ve always used Gravity Forms, so this is exciting.

I’ve been watching the Youtube videos, and I think I’m replicating what he’s doing in the video, but I’m having two issues with the Tippet Contact Form:

  1. It’s not submitting the data to Cornerstone > Forms Submission on the back end even though Ajax is selected
  2. It’s not emailing me a notification, even though I have that set up.
  3. Instead of the conditional thank you message appearing, it seems to be redirecting (even though I’m not using the redirect action) and it’s landing at an unknown page message, even though the URL is still the same /contact/ URL.

Help!
