Problem with IFRAME scroller JS

[M rosi]

Hello,
i'm trying to post news on my site. so i modified this http://www.dynamicdrive.com/dynamici...e-scroller.htm

this is the modified page http://www.shmtestforums.uphero.com/...ller/test.html

but i couldn't get, exactly what i want. i really want is

• when load the page it should shows only 3 rows

• then after few seconds(say 2 seconds), the 1st row should disappear and bellow 3 rows should come up
  (eg. when dynamicdrive_1 row is disappear, dynamicdrive_2 & dynamicdrive_3 & dynamicdrive_4 rows should come up)

• this rotation should be continuous

i tried this many. but no positive result.
please help me.

this is the problematic java script

<script type="text/javascript">

var scrollspeed=cache=1
var initialdelay=500

function initializeScroller(){
	dataobj=document.all? document.all.datacontainer : document.getElementById("datacontainer")
	dataobj.style.top="5px"
	setTimeout("getdataheight()", initialdelay)
}

function getdataheight(){
	thelength=dataobj.offsetHeight
	if (thelength==0)
		setTimeout("getdataheight()",10)
	else
		scrollDiv()
}

function scrollDiv(){
		dataobj.style.top=parseInt(dataobj.style.top)-scrollspeed+"px"
		if (parseInt(dataobj.style.top)<thelength*(-1))
			dataobj.style.top="5px"
		setTimeout("scrollDiv()",40)
}

if (window.addEventListener)
		window.addEventListener("load", initializeScroller, false)
else if (window.attachEvent)
		window.attachEvent("onload", initializeScroller)
else
		window.onload=initializeScroller

</script>
