How can I show a resume of data inserted by every user?

I need to give to user a resume of their submission, how can i do that?

If you want your user to see the data before they submit the form you can use the Preview before submit widget:

If instead, you want to send to your user a copy of the filled in form you can setup an auto-responder:
