Generating a Document

I want to generate a document using DocuSign and I know with the fillable PDF you can use information gathered from form entries for the PDF document. My problem is that I cannot get DocuSign to pull in the email's from the contact lists columns. It is my understanding that this is a possibility but I just cannot get it to work. I have done several searches and tried a few different fixes but still not able to get it to work. Any help would be much appreciated.
