Jason, thank you for taking the time to test my files.
I went back to testing my files again, and still I am running into the same problem. The address fields are not showing up in the body of the email. I even tried using a new template in UE (Blank.php) to see if the template I was using previously was the problem. It did not make a difference - the address fields were left out.
Here is what I am uploading to my server:
2. waue_cu_registration_2.php (I updated the UE server behavior a second time to start fresh)
3. cu_registration.php (email template file)
4. cu_registration.php (actual web form)
Is there anything I am leaving out?
