I have been trying to set up merge mapping to merge salesforce fields with my template. I have created an agreement using an attached doc with the tags shown below. I can send and sign that doc. I then create a new merge mapping and import the signed doc. It imports 6 fields but they are all echosign fields (first name, last name, title, etc). None of the fields that I defined in the doc are showing up. What am I doing wrong?
