Default Failed to convert parameter value to Decimal Guid

In Chapter 10: Building Business Logic and Data Access Components, I get the following error:

Failed to convert parameter value to Decimal Guid
The error originates from the logical layer, in this part of the code

Public Function AddGroup(ByVal Group As DataSet) As Boolean

'Llama al componente de datos para añadir un estado
Return objWDAGroups.AddGroup(Group)
Catch ExceptionErr As Exception
Throw New System.Exception(ExceptionErr.Message, ExceptionErr.InnerException)
End Try

End Function
Please help me.
