Как проверить мои поля переключателей с помощью magento?

Я создал форму, но я мог бы проверить свои поля переключателей. Когда я нажимаю на "Отправить", он не показывает никакого символа предупреждения.

Если переключатель не выбран, он должен отображаться как на изображении для переключателя. пожалуйста, кто-нибудь, помогите мне.

Моя форма
