Cannot use on html page?
I had the same problem, then created a php page and Universal Email opened fine. But I am rather disappointed as this was supposed to be easy to use and I wanted to use it on my html forms. So now I have to use all my forms in php? Surely I am missing something here.
Trying to use this in conjuction with CSS FormBuilder, which does not require you to go to php to create a form. Thought this would just add the verification and database functionality to exiting forms.
