VBA Lock rows upon checkbox click on multi-sheets

[kennethshuen]

Hi guys,

I would like to make a code in VBA that locks the entirerow whenever the checkbox is checked on both sheet 1 (starting from row 3), sheet 2 (starting from row 4). What I did now was using the code below on sheet 2, and using formular [=IF('sheet 2 defined cell value <>"", "1","")] on sheet 1 to try to prompt the same code with another private sub. But apparently that doesn't work as planned and the code below isn't perfect as well. Please comment below for any ideas!!! Thank you guys!

Private Sub Worksheet_Change(ByVal Target As Range)
Dim a As Long


    If Not Intersect(Target, Columns("P")) Is Nothing Then
        ' the changed cell is in column P
        If Target.Cells.Count = 1 Then
            ' only act if it is a single cell, so multicell copy will not trigger this
            If Target.Value <> "" Then
                Me.Unprotect Password:="123"
                Target.EntireRow.Locked = True
                Me.Protect Password:="123"
            Else
                Me.Unprotect Password:="123"
            End If
        End If
    End If
End Sub
