Hi Tim, I found the error, cuentaInventario was declared of the following way: Productocuentacontable cuentaInventario ; and it had to be declared of the following way: Productocuentacontable cuentaInventario = new Productocuentacontable(); and that corrected the problem. > Probably a silly question, but does cuentaInventario have setters defined > for prod_id and cc_id?
