Thanks for reaching out @mialopes. If you edited the templates to add or change fields, you’ll also need to include code on the backend to handle processing and storing that data. There are a ton of different approaches folks can take to that, but generally you’ll use WordPress hooks to grab the data, clean it up, then put it in the database however you’d like.
Coding is outside the scope of our support here, so if you don’t have a ton of programming experience it may be helpful to work with a WordPress developer to get it all working.
If you have any other basic questions, don’t hesitate to let us know. We’re happy to help.
Since we haven’t heard from you in a little while I’m going to mark this thread resolved. Don’t hesitate to reach out if any other questions come up in the future!
