Thanks, Jeff --

I think I'm closer. I confess to being a newbie when it comes to using
functions in Access. If I misunderstood your advice below, I
apologize. I didn't have any luck with the CStr() function, but I
finally got my form to look as desired by putting the following in my
Control Source for the field: =Format([Figure Identifier],"0000000" &
[Description] & ".eps"). So far, so good.

The table tied to the form was imported in Access from Excel, and the
form was then built on the table.  Within the table, however, this
field is not populating when adding new records. Only the initial row,
which was populated at the time of the import, still shows visible
data.

FWIW, the two fields in the table do not have identical formatting in
Access -- the formatting is the way Access interpreted it upon import.

I would like the Figure Identifier Description field to populate in
the table, too, though this is perhaps not absolutely essential. What
is your advice for next steps?
