Обзоры продуктов в шаблоне продукта nopcommerce

Я пытаюсь добавить Product.Reviews.cshtml, который дает пользователю возможность ввести свой отзыв о продукте. Кому Product.Template.Simple.cshtml, который отвечает за отображение пользовательского изображения продукта и всей информации.

но ошибка вызвана тем, что не может быть две модели в одном файле..
