I developed the following macros using Excel 2002 running on Windows XP
Professional -

If dir("C:\File_Name.txt")< "" then
my_data = mid(input,1,4)
Endif

When I execute the macro using Excel 1997 SR2 running on Windows 98 an error
message pops up - 'Can't find project or library'

This greek to me. Can someone tell me I have done wrong and how to rectify
this situation.

Thank you.
