Javascript-форум - не работает JavaScript в div"е

Есть страничка на ней надо вывесть таблицу которая при навидении курсора выделяет строку(используя JavaScript).

Проблема:
при отрытии demo.php всё ОК, но когда загружаю через div на форме загружается только статическая таблица(JavaScript не работает)

Как можно решить данную проблему :confused:
