Problem solved. Even though the ufMain.Show line was identified as the
offending problem, the form was trying to load a value that wasn't there. So
the offending line was really elsewhere in the code.

I'm trying to load a user form:

Sub ShowUFMain()
ufMain.Show
End Sub

I get a Microsoft Visual Basic dialog box:
Run-time error '-2147352571 (80020005)':
Type mismatch

This was working earlier. What to do???
