This may have already been covered, but is there a typo in the GetOrderDetail() method of the OrderDetail class in the Jump Start, version 1.3?

' Returns a DataSet containing all order items for the specified order
Public Function GetOrderDetail(ByVal orderID As Integer) As DataSet
    Return Me.GetDataSet("SELECT * FROM " + Me.SourceTable + " WHERE OrderID = @OrderID", _
      Me.CreateParameter("@OrderID", orderID))
End Function

Me.SourceTable is undefined. Should this be a field in class, or am I missing something?
