Auto-Scrolling dynamic XML content in Frame

[admin]

I have built a frames page that has one section that points to the data display of an Access Query exported as XML with the XML and XSL files in the web root folder. I need to insert a javascript that autoscrolls the frame that contains this display. Here is the scrolling JS

<SCRIPT language=JavaScript1.2>
//change 1 to another integer to alter the scroll speed. Greater is faster
var speed=1
var currentpos=0,alt=1,curpos1=0,curpos2=-1
function initialize(){
startit()
}
function scrollwindow(){
if (document.all)
temp=document.body.scrollTop
else
temp=window.pageYOffset
if (alt==0)
alt=2
else
alt=1
if (alt==0)
curpos1=temp
else
curpos2=temp
if (curpos1!=curpos2){
if (document.all)
currentpos=document.body.scrollTop+speed
else
currentpos=window.pageYOffset+speed
window.scroll(0,currentpos)
}
else{
currentpos=0
window.scroll(0,currentpos)
}
}
function startit(){
setInterval("scrollwindow()",50)
}
window.onload=initialize
</SCRIPT>

My problem is the scroll works on a plain HTML file but not on the HTMcreated when exporting as an XML.

Any suggestions?
