Стрелочки слайдера не работают. Ошибок никаких нет

Почему не работает переключение - я не понимаю. Функции следующий и назад написаны. Я их в код установил. Ошибок никаких нету. Проверял с выводом в консоль сообщения и цифры, всё работало +1 -1 и так далее. Но слайдер не переключается. И вообще никак не реагирует.
