Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
If Not Intersect(Target, Range("F10:F1000")) Is Nothing Then
    If Range("$M$3") > 0 Then
        MsgBox "Number Is Not Valid  " & Target.Value
        Application.EnableEvents = False
        Target.ClearContents
        Application.EnableEvents = True
        Exit Sub
    End If
End SuB
