type missmatch on Selection.Offset

[webby2006]

Sub DuplicateColumns(iOffset1 As Integer, iOffset2 As Integer)
   
    Selection.Offset(iOffset1 & ", " & iOffset2).Select
    
End Sub

Call DuplicateColumns(0, 3)

I am getting type missmatch. What is the correct data type should I be passing as argument?

Thank you.
