Я пытаюсь использовать переменную из editselection для редактирования количества, например, когда пользователь вводит значение, оно добавляет его в корзину с файлами и «вычитает», если хотите, из запасов файлов, использование глобального недоступен из-за того, что меня просто пометят. Я застрял на этом уже 2 дня
