I want to use a standard 'Word' field in my Excel header

[Gail]

When I create a Word document, I can utilise various 'merge fields' from
other programs as part of my template. The other program I extract the
information from is written in Foxpro (it is an accounting practice
management program)

I want to do the same thing in an Excel file, but do not seem to be able to
use the same functionality.

Can anyone give me any clues please - I am only a moderately experienced
Excel user.
