I have a mail merge document that was created in Word 2002 that I now need to
use in Word 2003 with a different portion of the full database. When I open
the document and go through the steps to create the mail merge, everything
appears to be fine. I see only the recipients I expect to see. However, when
I click on preview your letters, I see everyone in the database (an Excel
sheet). Moving on through the steps also results in my getting everyone in
the database.

I thought 2003 was supposed to be backward compatible. How do I work around
this obvious problem without having to recreate my document from scratch?
