|I can produce a:|
Run-time error '53': File not found
if the file doesn't exist in the path, or an
Run-time error '76': Path not found
if the path doesn't exist.
I can't seem to produce a "Missing Files" error.
A quick Google search didn't return any hits for a VBA Shell "Missing Files" error, but does for "File not found" and "Path not found".
Can you supply your exact code so we can take a look at it?
