The code below automatically scrolls a page after load. What im trying to do is get the code to automatically scroll a set iframe built into the page. given that i have named the iframe.

thx for any help in this matter.

[CODE]<script language=”JavaScript1.2″>
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=1
else
alt=0
if (alt==0)
curpos1=temp
else
curpos2=temp
if (curpos1!=curpos2){
if (document.all)
currentpos=document.body.scrollTop+1
else
currentpos=window.pageYOffset+1
window.scroll(0,currentpos)
}
else{
currentpos=0
window.scroll(0,currentpos)
}
}
function startit(){
setInterval(“scrollwindow()”,10)
