As mentioned on the previous thread, I took a look at the same form as before: http://form.jotformpro.com/form/52844963978981, but the email at this time only shows: "undefined" as the email content.

I would suggest removal of current and creating new one, but both ways should work just the same.
These two guides will help you with this:
