请高人指教为什么jquery语句老是提示错误呢？

具体

<div class="flashbanner">

<SCRIPT language=javascript type=text/javascript>

var photos31=[

["http://www.wholesale-gucci.com/images/categories/575x180.jpg","wholesale-prada","#"],["http://www.wholesale-gucci.com/images/categories/575x180.jpg","wholesale-prada","#"],["http://www.wholesale-gucci.com/images/categories/575x180.jpg","wholesale-prada","#"],["http://www.wholesale-gucci.com/images/categories/575x180.jpg","wholesale-prada","#"]];</SCRIPT>

<DIV id=focusViwer31>

</DIV>

<DIV style="PADDING-BOTTOM: 10px; MARGIN-TOP: 0px" id=bannerAdCenterTOP

class="txtBanner noMarginTop">

<SCRIPT type=text/javascript>

var numStr = "";

for (var i = 1; i < photos31.length + 1; i++){numStr += ("<li><span class='numVal'>" + i + "</span></li>");}

var html = '<div id="TopAD" class="slideBanner" style="display:none;height:180px;"><ul class="img"></ul><div class="panel"></div><ul class="num">' + numStr + '</ul></div>';

$("#focusViwer31").append(html);

imgPlayerTopAndMidIndex("TopAD", photos31);

var interval31 = setInterval('showNumImg("TopAD")', 6000);

$("#focusViwer31>a").remove();

$("#TopAD").show();

$("#TopAD").mouseenter(function() { clearInterval(interval31); });

$("#TopAD").mouseleave(function() { interval31 = setInterval('showNumImg("TopAD")', 6000);});

</SCRIPT>

</DIV>

</div>

把这段代码替换www.wholesale-prada.com 上的flash banner图片切换的老是出现：
