Hi
Put the following code in your worksheet module:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
If Intersect(Target, Me.Range("A1")) Is Nothing Then Exit Sub
On Error GoTo CleanUp
application.enableevents = false
With Target
If .Value <> "" Then
Me.Name = .value
End If
End With
CleanUp:
Application.EnableEvents = True
End Sub
