Private Sub Worksheet_SelectionChange(ByVal Target As Range)

Good day,
Will like to use these 2 codes in the work sheet. It gives ambigous error in the 2nd code 1st line - Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Kindly suggest what to write in tht line or how to use these 2 codes together.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    
    'another method is to have it show if a cell that is formatted as a date is selected...see below
    If Target.NumberFormat = "m/d/yy;@" Then
        CalendarFrm.Show
    End If
      
    'another method is using Select Case...see below
    Select Case Target.NumberFormat
        Case Is = "m/d/yy", "m/d/yyyy", "m/d/yy", "mm/dd/yy", "yyyy-mmm-dd", "dd-mmm-yy"
        CalendarFrm.Show
        'Case Else
        '    MsgBox "Not a valid date format!"
    End Select
End Sub
......................................................................................................................
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Me.ScrollArea = "A1:AX252"

End Sub

Thanks in advance
