LOL how do I offset my Combobox2?

Trying to use the same code

Dim LastRow1, LastRow2 As Long

Private Sub UserForm_Initialize()
    Caption = "Selection"
    
    LastRow1 = Worksheets("Sheet2").Range("A2").End(xlDown).Row
    ComboBox1.List = Worksheets("Sheet2").Range("A2:B" & LastRow1).Value
    ComboBox1.BoundColumn = 2
    
    LastRow2 = Worksheets("Sheet2").Range("B2").End(xlDown).Row
    ComboBox2.List = Worksheets("Sheet2").Range("B2:B" & LastRow2).Value ' What will B2:??? become
'    ComboBox2.BoundColumn = 2 'how do I offset the BoundColumn to look in A?


End Sub

Private Sub ComboBox1_Change()
    ComboBox2.Value = ComboBox1.Value
End Sub

Private Sub ComboBox2_Change()

End Sub
