Populating customer data within a document
I am in possession of a certain list that contains some data about our customers for example their first, middle and last names, address details and would like to populate this info within a document. The problem is that I am unable to come up with a way to add fields for the additional columns in the lookup column. I am using various data from the list as fields but currently all my efforts are yielding no result. If someone knows how to do this then I would really appreciate.
