Merge fields in Word updated automatically?

Hello,

I am running Word 2000 along with Access 2000 (with
Windows 98se). I have a simple address database in Access
(FirstName, LastName, Street, Zip, etc.) and want to
create tables in Word by merging (or "insert database").
I can do such, but I cannot figure out how to get the
table to update automatically when I change something in
the Access file.

I want to have several printable formats of this
infomation from Access. The people's names and numbers
are constantly changing, and I do not want to have to
recreate each Word document everytime someone's info is
updated.

How can I get a merged table to be updated automatically
when a field in Access changes or is updated?

Thanks and make it a great day!

Joe
