}
function startMarquee() {
var str=marqueeContent[marqueeId];
marqueeId++;
if(marqueeId>=marqueeContent.length) marqueeId=0;
if(document.getElementById("marqueeBox").childNodes.length==1) {

if(document.getElementById("marqueeBox").scrollTop%marqueeHeight==(marqueeHeight-1)){
clearInterval(marqueeInterval[1]);
}
}
initMarquee();
