All I can suggest is that you carefully check the field names in the
document against the column heading in Excel to make sure that they match
Exactly. Maybe best to get someone else to do it as it's very easy to
overlook something when you have done it a hundred times before.

I upgraded to Office 2003 and now when I try to merge records from an Excel
DB into a main WORD doc, I get the message "Merged field is used in the
main
doc but it does not exist in the data source."

This merge worked just fine hundreds of time in Office 2000.

I have tried using the MailMerge Helper button I placed in the bar but
that
didn't improve things.

Any suggestions for fixing this problem would be greatly appreciated. I
use
this merge a lot in my work.
