I have been playing with this for hours.
I am sending a zip file with both contact forms.
The 1st one works correctly. That is the only one that works. I can make changes to it and it's done. It won't work anymore. I can install it again and it works.
The 2nd one is the 1st, but modified with one more element call last name again. The form will not work and it keeps coming up with nothing in it but the form.
The 1st one will go to the thank you page. Here is the web address for the bad form page.
