Mike,

The problem is that if c is nothing, c.Address will fail with an
error 91. Try something like the following:

Dim C As Range
Dim FirstAddress As String
Dim Done As Boolean

With Worksheets(1).Range("a1:a500")
Set C = .Find(2, LookIn:=xlValues)
If Not C Is Nothing Then
FirstAddress = C.Address
Do
C.Value = 5
Set C = .FindNext(C)

If C Is Nothing Then
Done = True
Else
If C.Address = FirstAddress Then
Done = True
End If
End If

Loop While Done = False
End If
End With

Hi. The following Loop works well until all of the items
have been replaced. In the final loop, I receive the
following error: "Object variable or With Block Variable
not set."

Any ideas?

Thanks,
Mike.
