Thank you Doug, but
the problem is that I have to repair to bad things done by our
customers. That is, I receive a MailMerge Word document and its data
source in Excel format. And you can't even imagine what our customers
can call the header fields in the Excel file!!! Something like "Company
Name", or "Citta' ", or even "Fax. number " (yes, with all
those trailing spaces!!!)
Thus, I really have to know the general rule for matching Word fields
and the corresponding Excel fields!

Thank you
Alessio
