Embedding Route Maps

Dear Sirs,

I am using the advanced layout generator. I ahve to as I want a menu widget on the right hand site. We are trying to embed some maps into the site. We have tried using the text block and also treid using the code block. Here is the code we are using <iframe src=”//plugin.routeyou.com/routeviewer/free/?language=en&params.route.id=83090″ width=”100%” height=”600″></iframe>. However if we edit the page the embeded code seems to corrupt to <iframe src=”//plugin.routeyou.com/routeviewer/free/?language=en¶ms.route.id=83090″ width=”100%” height=”600″></iframe> and no longer works which is really annoying and the maps just show us Europe !! Not the route. Can you help please
