Don't understand how to add a recipient in autoresponder. There is only a dropdown.

Don't understand how to add a recipient in autoresponder. There is only a dropdown. I am trying to set up a form which the user can partially fill out and return to later.

Then in step 9, you write, "Paste the MAIN FORM's URL here (the one you copied from STEP 4)." Probably obvious to you, but where is "here"?  Is it at the end of what I wrote in step 8 or in the box below it?

In 9, There is the line: "While your mouse cursor is right beside the equal sign, click FORM FIELDS > then the EMAIL field to place the Unique Name of the email field at the end of the URL. 

What goes in the "Unique Name" Does the unique name need to be related to the First Form or Main Form or will any name do?

Recipient of the Autoresponder Email should be the form's Email field. 

Setting up an Autoresponder Email

I inspected the Autoresponder Email of your Candidate Questionnaire form and the Recipient Email is set properly. 

However, the session link you added to the body of the Autoresponder Email is incorrect. You added the link of the second form from the Form Builder and it should be a link of the live form.
