Hey
OK - there are 2 ways of doing this. The first way is the way you requested using Javascript on the page that hosts the IFRAME. I have written and tested the code and there is an example below.
However, the second method is the more accepted, "correct" method. This method involves using the meta refresh tag in the document that you wish to reload, ie the document that gets loaded into the IFRAME. Obviously if you are loading a page from another website into your IFRAME, you will not be able to change their page code, so the Javascript option is the only option you have. However, if the page being displayed and refreshed is under your control, I would strongly suggest using this method.
Simply include the following in the HEAD of your document:
CODE
<meta http-equiv="refresh" content="3">
That will tell you browser to refresh the page every 3 seconds. Simple!
If you have to use the Javascript method, you can try the code below. I have included the code of the whole test page, so you can copy and paste this into a new .htm document and run it immediately:
CODE
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="pl" xml:lang="pl">
<head>
<title>Javascript IFrame Reload</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script type="text/javascript"><!--
// set your interval in milliseconds
var reloadInterval = 3000;
// this will run when the document is fully loaded
function init() {
setTimeout('reload()',reloadInterval);
}
// this reloads the iframe, and triggers the next reload interval
function reload() {
var iframe = document.getElementById('reloader');
if (!iframe) return false;
iframe.src = iframe.src;
setTimeout('reload()',reloadInterval);
}
// load the init() function when the page is fully loaded
window.onload = init;
--></script>
</head>
<body>
<iframe id="reloader" width="500" height="400" src="http://www.google.com/"/>
</body>
</html>
Hope that helps.

Excellent, Excellent! Thank u peeps from the bottom of my slightly mis-understood heart! THe javascript worked excellent I had previously tried the meta refresh tag but could not get it to work, but then I had the bright idea of using the meta tag and seeing if it worked in othe browsers like mozilla and firefox and what do ya know it did! Now all I have to do if figure out why the meta refresh is not working in 
IE 
I called the hosting company to see if they could help me figure it out but none of their workstations have IE, they use linux with mozilla! But the tech is gonna play with it on his comp at home and see if its just a bad install on my machine or if it is a IE issue. Ah enough rambling this thing is gonna go live next week and u guys saved my buttocks so thanks again!
