JS-də səhv var

Salam saytımda js problemi var. kohnə versiya İnternet explorer işlədəndə bunun şahidi oldum. Elə bildim css səhvidir amma sonra isə firofoxun firebug pluginin yukledim.ve 2 JS faylinda səhv tapıldı.Bunu saytı söyləmədən kodu bura daxil etsəm kömək edə bilərsiz?

prtotype.js faylında 3840 sətirdə səhv var.firebug sehvi bele gosterir:
handler is undefined
handler.call(element, event) -aşağıdakı kodda bu bəndi axtarın.yəni 3840-cı bənddir bu-
