Can you point me in the right direction please. I am creating a form that will either have a Drop Down or Radial choice of Yes and No. If the user selects "yes" then I would like to pop a message up with just and OK button. This popup is just for acknowledgement stating "you selected this .... you must do this..".. I have searched google/internet and did a search here but I do not see what I might be looking for for SharePoint Online/O365 with Nintex Forms. If I do just a regular validation in rules, that will stop the form from submitting and I do not want that.
