Excel 97 VBA: tracing a run time error
 

I have developed a user form that allows a user to enter
some information, which is inserted into a spreadsheet and
then sent to an email address using the routing slip
concept.

However, on some users PCs the process fails with the
following error:

-
Run-time error '-2147024809 (80070057)':
The item with the specified name wasn't found.
-

This error is PC specific not user profile or data entry
specific. Does anyone have any idea what item it may be
that's not found or how I can trace the issue?

Many thanks
