Javascript Vertical Scroll Bar For Asp.net

The Script :
<script type="text/javascript">
var delayb4scroll = 2000 //Specify initial delay before marquee starts to scroll on page (2000=2 seconds)
var marqueespeed = 1 //Specify marquee scroll speed (larger is faster 1-10)
var pauseit = 1 //Pause marquee onMousever (0=no. 1=yes)?

////NO NEED TO EDIT BELOW THIS LINE////////////

var copyspeed = marqueespeed
var pausespeed = (pauseit == 0) ? copyspeed : 0
var actualheight = ''

function scrollmarquee() {
if (parseInt(cross_marquee.style.top) > (actualheight * (-1) + 8)) //if scroller hasn't reached the end of its height
cross_marquee.style.top = parseInt(cross_marquee.style.top) - copyspeed + "px" //move scroller upwards
else //else, reset to original position
cross_marquee.style.top = parseInt(marqueeheight) + 8 + "px"
}

function initializemarquee() {
cross_marquee = document.getElementById("vmarquee")
cross_marquee.style.top = 0
marqueeheight = document.getElementById("marqueecontainer").offsetHeight
actualheight = cross_marquee.offsetHeight //height of marquee content (much of which is hidden from view)
if (window.opera || navigator.userAgent.indexOf("Netscape/7") != -1) { //if Opera or Netscape 7x, add scrollbars to scroll and exit
cross_marquee.style.height = marqueeheight + "px"
cross_marquee.style.overflow = "scroll"
return
}
setTimeout('lefttime=setInterval("scrollmarquee()",30)', delayb4scroll)
}

if (window.addEventListener)
window.addEventListener("load", initializemarquee, false)
else if (window.attachEvent)
window.attachEvent("onload", initializemarquee)
else if (document.getElementById)
window.onload = initializemarquee
</script>

The Css:
<style type="text/css">
#marqueecontainer
{
position: relative;
width: 200px; /*marquee width */
height: 200px; /*marquee height */
background-color: white;
overflow: hidden;
border: 3px solid orange;
padding: 2px;
padding-left: 4px;
}
</style>

<body>
<form id="form1" runat="server">
<div id="marqueecontainer" onmouseover="copyspeed=pausespeed" onmouseout="copyspeed=marqueespeed">
<div id="vmarquee" style="position: absolute; width: 98%;">
