I am mapping Typeform and SF for our e-survey. The first 4 questions are First name, Last name, phone # and Email and I want to map them with the Contact object in SF. The rest of questions are actual survey questions and I want to map with the Support Survey object which is our custom object. In the Support Survey object, we have the “Contact” feild as below.

However, when I am mapping these filed, I can’t see them on the pulldown list.

How can I map them?
(All questions I created under the Support Survey object are showing correctly.)
Thanks!
