AggregateRating error on Structured Data Testing Tool

Hi Chan

I’m testing some of my articles with Structured Data Testing Tool and I’m getting the following message (in spanish): “La reseña no tiene ningún elemento con reseña especificado” (in english would be something like: “The review does not have any element with review specified”)

For example one of the link that I’m testing is http://www.gestiondeoperaciones.net/plan-de-requerimientos-de-materiales/ejemplo-del-plan-de-requerimientos-de-materiales-mrp/

Thanks in advance for your help
