Glad to have helped.

Word has a bunch of great features but finding out about them can be tough.
AutoText and the other Building Blocks are real gems. Quick Parts is one such Building Block as well as being the generic title/button that Word uses to get to a number of features including fields. Personally, I would save it in the Text Box gallery.
