Accessing the PageRequestManager when Page is iFramed

I have a page that has a scriptmanager, updatepanel, and timer in it. This page is iframed by another page on another domain. I'm trying to override what happens when the update panel / asynch post back has an error like so:

<scripttype="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_endRequest( endRequest );
function endRequest( sender, e ) {
if( e.get_error() ){
}
}
</script>

Per Luis' post here:http://msmvps.com/blogs/luisabreu/archive/2006/10/29/UpdatePanel_3A00_-having-fun-with-errors.aspx

This seems to work fine but when the page is iframed in i get the following javascript error:

'Sys' is undefined.

Any ideas on how to fix this?

Thanks
