To confirm, you would like to use the "Next" button to submit the data that your users has entered on each page?
Unfortunately, it is not possible to use the next button as a submit button.
You can however, create multiple forms and set a submit button with the text "Next" and have your users directed to the next page (another form). You would use your forms URL as for the "Custom URL" option for your "Thank You" page.
I hope this helps, please inform us if you need further assistance.
