Не работает Java Script | Форум Mozilla Россия

Всем привет. Поменял код так: zakaz_cost на document.getElementById('zakaz_cost') (и так заменил все id). Вставил в Joomla. Теперь в Firefox частично заработало, но при весе больше 2.27кг не показывает расчитанную сумму
Вне джумлы код по прежнему исправно работает под Firefox.
Если можете, посмотрите правильно ли заменил id на document.getElementById.
