I am using an iframe code to link to a center content in another 
domain using the following code-

<IFRAME id="whereToBuyApp" src="http://www.washingtonpost.com" 
scrolling="no"  width="555" frameborder="0" >Sorry, your browser 
doesn't support iframes.</iframe>

The height of the iframe is getting set automatically by this script-
<script type="text/javascript">

//Input the IDs of the IFRAMES you wish to dynamically resize to match 
its content height:
//Separate each ID with a comma. Examples: ["myframe1", "myframe2"] or 
["myframe"] or [] for none:

var iframeids=["whereToBuyApp"]

//Should script hide iframe from browsers that don't support this 
script (non IE5+/NS6+ browsers. Recommended):
var iframehide="yes"

var getFFVersion=navigator.userAgent.substring
(navigator.userAgent.indexOf("Firefox")).split("/")[1]
var FFextraHeight=parseFloat(getFFVersion)>=0.1? 16 : 0 //extra height 
in px to add to iframe in FireFox 1.0+ browsers

function resizeCaller() {

var dyniframe=new Array()
for (i=0; i<iframeids.length; i++){
if (document.getElementById)
resizeIframe(iframeids[i])
//reveal iframe for lower end browsers? (see var above):
if ((document.all || document.getElementById) && iframehide=="no"){
var tempobj=document.all? document.all[iframeids[i]] : 
document.getElementById(iframeids[i])
tempobj.style.display="block"

}
}
}

function resizeIframe(frameid){

var currentfr=document.getElementById(frameid)
if (currentfr && !window.opera){

currentfr.style.display="block"
if (currentfr.contentDocument && 
currentfr.contentDocument.body.offsetHeight) {//ns6 syntax

currentfr.height = 
currentfr.contentDocument.body.offsetHeight+FFextraHeight;
}
else if (currentfr.Document && currentfr.Document.body.scrollHeight) 
{ //ie5+ syntax

currentfr.height = currentfr.Document.body.scrollHeight;
}
if (currentfr.addEventListener){

currentfr.addEventListener("load", readjustIframe, false)
}
else if (currentfr.attachEvent){

currentfr.detachEvent("onload", readjustIframe) // Bug fix line
currentfr.attachEvent("onload", readjustIframe)
}
}
}

function readjustIframe(loadevt) {

var crossevt=(window.event)? event : loadevt
var iframeroot=(crossevt.currentTarget)? crossevt.currentTarget : 
crossevt.srcElement
if (iframeroot)
resizeIframe(iframeroot.id);
}

function loadintoIframe(iframeid, url){

if (document.getElementById)
document.getElementById(iframeid).src=url
}

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

//-->

</script>



But I keep getting a "Permission denied" error which keeps pointing to 
this line in the javascript-
"else if (currentfr.Document && currentfr.Document.body.scrollHeight) 
{ //ie5+ syntax "


Could someone please let me know what I am doing wrong...

thanks,
Rams
