I need to simplify a contract creation process. The document exists in Word.
I would like to add fields that will repeat throughout the document, based on
the first field. For instance - where the first field states the client's
name, I want to be able to tag fields throughout the rest of the document to
copy that field so I don't have to fill in the client's name in the different
part of the contract over and over.

I'm guessing I need to assign a macro to run on entry for each field, but I
have no clue about how to write macros. Any help would be GREAT. Thanks.
