Olá!
Achei um código em javascript de uma janela flutuante muito interessante que roda 4 banners, só que estou com um problema a janela não esta flutuando, ela fica estatica onde coloco o js na minha página html. Como não entendo de javascript gostaria que alguem com conhecimento me ajudasse. Segue abaixo o código:

on closeDiv() {
document.getElementById('floatLayer').style.left = "-1000";
return false;
}

var how_many_ads = 4;
var now = new Date()
var sec = now.getSeconds()
var ad = sec % how_many_ads;
ad +=1;
if (ad==1) {
url="http://www.pagina1.htm";
banner="http://www.foto1.jpg";
}
if (ad==2) {
url="http://www.pagina2.htm";
banner="http://www.foto2.jpg";
}
if (ad==3) {
url="http://www.pagina3.htm";
banner="http://www.foto3.jpg";
}
if (ad==4) {
url="http://www.pagina4.htm";
banner="http://www.foto4.jpg";
}
window.onerror = null;
var topMargin = 10;
var slideTime = 3000;
var ns6 = (!document.all && document.getElementById);
var ie4 = (document.all);
var ns4 = (document.layers);

function layerObject(id,left) {
if (ns6) {
this.obj = document.getElementById(id).style;
this.obj.left = left;
return this.obj;
}
else if(ie4) {
this.obj = document.all[id].style;
this.obj.left = left;
return this.obj;
}
else if(ns4) {
this.obj = document.layers[id];
this.obj.left = left;
return this.obj;
}
}

function layerSetup() {
floatLyr = new layerObject('floatLayer', pageWidth * .11);
window.setInterval("main()", 10)
}

function floatObject() {
if (ns4 || ns6) {
findHt = window.innerHeight;
} else if(ie4) {
findHt = document.body.clientHeight;
}
}

function main() {
if (ns4) {
this.currentY = document.layers["floatLayer"].top;
this.scrollTop = window.pageYOffset;
mainTrigger();
}
else if(ns6) {
this.currentY = parseInt(document.getElementById('floatLayer').style.top);
this.scrollTop = scrollY;
mainTrigger();
} else if(ie4) {
this.currentY = floatLayer.style.pixelTop;
this.scrollTop = document.body.scrollTop;
mainTrigger();
}
}

function mainTrigger() {
var newTargetY = this.scrollTop + this.topMargin;
if ( this.currentY != newTargetY ) {
if ( newTargetY != this.targetY ) {
this.targetY = newTargetY;
floatStart();
}
animator();
}
}

function floatStart() {
var now = new Date();
this.A = this.targetY - this.currentY;
this.B = Math.PI / ( 2 * this.slideTime );
this.C = now.getTime();
if (Math.abs(this.A) > this.findHt) {
this.D = this.A > 0 ? this.targetY - this.findHt : this.targetY + this.findHt;
this.A = this.A > 0 ? this.findHt : -this.findHt;
}
else {
this.D = this.currentY;
}
}

function animator() {
var now = new Date();
var newY = this.A * Math.sin( this.B * ( now.getTime() - this.C ) ) + this.D;
newY = Math.round(newY);
if (( this.A > 0 && newY > this.currentY ) || ( this.A < 0 && newY < this.currentY )) {
if ( ie4 )document.all.floatLayer.style.pixelTop = newY;
if ( ns4 )document.layers["floatLayer"].top = newY;
if ( ns6 )document.getElementById('floatLayer').style.top = newY + "px";
}
}

function start() {
if(ns6||ns4) {
pageWidth = innerWidth;
pageHeight = innerHeight;
layerSetup();
floatObject();
}
else if(ie4) {
pageWidth = document.body.clientWidth;
pageHeight = document.body.clientHeight;
layerSetup();
floatObject();
}
}
document.write('<DIV id=floatLayer style="position: absolute; width: 10; height: 10; z-index: 10; left: 10; top: 10; visibility: visible; border: 0px none #000000">');
document.write('<table border="0" cellspacing="0" cellpadding="0" bordercolor="#FFFFFF">');
document.write('<tr><td border="0" align="center" bgcolor="#ffffff" colspan="4">');
document.write('<a onClick=closeDiv() href=' + url + ' target=_blank "\return false\">');
document.write('<img src=' + banner + ' ')
document.write('border=0></a></td></tr>');
document.write('<tr><td border="0" align="right" colspan="4"><input type="submit" name="fechar" value="Fechar" onClick="return closeDiv()" style="font-family: Verdana; font-weight: bold; font-size:10px; color: #FFFFFF; background-color: #000000; border: 1px solid #000000;"></td></tr>');
document.write('</table></DIV>');
start();


desde já agradeço.
