有问题请教，IE8.0"网页上有错误"

我程序是用asp写的，用IE7浏览网站很正常，改用IE8就出现"网页上有错误"，如下图:


js代码如下：
<!-- Beginning of JavaScript Code -------------------

nereidFadeObjects = new Object();
nereidFadeTimers = new Object();
function nereidFade(object, destOp, rate, delta){
if (!document.all)
return
    if (object != "[object]"){ setTimeout("nereidFade("+object+","+destOp+","+rate+","+delta+")",0);
        return;
    }
    clearTimeout(nereidFadeTimers[object.sourceIndex]);
    diff = destOp-object.filters.alpha.opacity;
    direction = 1;
    if (object.filters.alpha.opacity > destOp){
        direction = -1;
    }
    delta=Math.min(direction*diff,delta);
    object.filters.alpha.opacity+=direction*delta;
    if (object.filters.alpha.opacity != destOp){
        nereidFadeObjects[object.sourceIndex]=object;
        nereidFadeTimers[object.sourceIndex]=setTimeout("nereidFade(nereidFadeObjects["+object.sourceIndex+"],"+destOp+","+rate+","+delta+")",rate);
    }
}
// -- End of JavaScript Code -->

鼠标移到菜单栏就出现错误，估计是这JS代码有问题，请大家帮帮忙。
