склад № 2

Я пытаюсь продать товар со склада_id 2, где у меня есть 43 товара на складе, где он показывает запас, когда я продаю 1 или 2 количества с этого склада, я не знаю, какой кусок кода вызвал проблему.

Проблема количества вполне вероятна в этом коде, так как я спрашивал технику о проблеме, но они сами не знают, какая часть кода вызывает проблему.
