Auto resize an iframe for an external site

Hi. I have tried this using several diferent scripts I found online. I cant get any to work! the iframe is:

<iframe onload="window.scroll(0,0);" src="http://products.xelector.com/gab/Utilities/" name="GasElectric" id="GasElectric_iframe" scrolling="no" frameborder="0" width="802" height="1200"></iframe>

I have tried changing height to 100%
Tried jsscrip
Tried:
function resizeIframe(iframeID) {
if(self==parent) return false; /* Checks that page is in iframe. */
else if(document.getElementById&&document.all) /* Sniffs for IE5+.*/

var FramePageHeight = framePage.scrollHeight + 10; /* framePage
is the ID of the framed page's BODY tag. The added 10 pixels prevent an
unnecessary scrollbar. */

parent.document.getElementById(iframeID).style.height=FramePageHeight;
/* "iframeID" is the ID of the inline frame in the parent page. */
}


Tried:
<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=["maincntnt"]

//Should script hide iframe from browsers that don't support this script (non IE5+/NS6+ browsers. Recommended):
var iframehide="no"

var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf("Firefox")).split("/")[1]
var FFextraHeight=parseFloat(getFFVersion)>=0.1? 3 : 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)
//reveal iframe for lower end browsers? (see var above):
if ((document.all || document.getElementById) && iframehide=="no"){
var tempobj=document.all? document.all[iframeids] : document.getElementById(iframeids)
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>





NOTHING SEEMS TO WORK

i DO NOT HAVE ACCESS TO THE CONTENT OF THE IFRAME SO CAN'T ADD CODE TO THIS. CAN ONLY ADD ON THE PARENT PAGE. THE IFRAME IS CALLING ON A SITE FROM AN AFFILIATE PROGRAM AND I DOUBT THEY WOULD ADD CODE TO THE REPORT.
ALSO THE CODE ABOVE IS IN ITS BARE FORM PRIOR TO ALTERING WITH SPECIFICS FOR MY SITE.
