How do I send responses to the user submitting the Form?

Also, rather than submitting the information to us, the completed form should be send to the user at the email address they have provided. Can you help me do this as well?

To send the responses to the user on submitting the Form you would have to set up the autoresponse email:

Let us know if you have further questions.

Thanks.
