Mail Merge

I spent a good deal of time creating a letter template in LiveCycle with fields for date, name, address, salutation, etc.

I unveiled what I thought was a beautiful example of a user-friendly form letter PDF, then one of the employees within the intended user group expressed great dissatisfaction for the fact that he could no longer use the mail merge feature he was used to in MS Word.

I don't know anything about this MS Word function, and now am being asked to incorporate this into my LiveCycle form. Any help??

I'm not sure if this is something I have to manipulate in scripting (in LiveCycle), or designate in Acrobat, or a process I have to teach employees (like File>Import>Whatever).

Advice would be very much appreciated! :)
