Use the "Populate a Form Field" action to display answers (responses ) from answered questions (fields) using the {Token} option.
In a multi page form, it's often always a good idea to show a summary of user responses prior to submission. This allows a user to visually confirm their responses and go back and make changes if necessary.
This can be accomplished by using the Bind or update a single form field via JavaScript action and its {TOKEN} feature.
