Hi everyone,

I've had a good look around and I'm getting the impression that this isn't possible.

I want to add some classes to various bits on one of Worldpay's lovely payment iframes so I can make it look something like the site it's sat on.

This is the original principle I was using, which works when on a page with the same domain.

Code JavaScript:
$('#worldpay').load(function(){
		                    $(this.contentDocument).find('body').html('Test: This frame was modified with js')
 
});

Any ideas?
