Loop through column, range.copy to another sheet based on cell value

[vaemps]

I have code like this:

Private Sub CommandButton2_Click()


    Dim i As Long
    Dim r As Long
    Dim Rng1 As Range
    Dim Rng2 As Range
    Dim Rng3 As Range
    
    With Sheets("sheet1")
    Set Rng1 = .Range("A2", .Range("A" & Rows.Count).End(xlUp))
    Set Rng2 = .Range("M2", .Range("M" & Rows.Count).End(xlUp))
    Set Rng3 = .Range("L2", .Range("L" & Rows.Count).End(xlUp))
    End With
    For i = 3 To Rng1.Count * 6 Step 6

If Rng3.Value = 1 Then
    Sheets("sheet2").Range("A1:B5").Copy _
    Destination:=Sheets("sheet3").Range("A" & i)
Elseif Rng3.Value = 2 Then
    Sheets("sheet2").Range("A5:B9").Copy _
    Destination:=Sheets("sheet3").Range("A" & i)
End If

      r = r + 1
    Sheets("sheet3").Range("A" & i).Value = Rng1(r).Value
    Sheets("sheet3").Range("B" & i).Value = Rng2(r).Value
      
    Next i
    
End Sub

Everything else I want is working properly, as it loops columns and inserts correct data to columns A and B. For the range.copy function I cannot get to work as I want it to. I want it to loop through column L and select correct range for copy based on that value. How I get this to work?
