1) On locating YouTube Code: It says to find the code that is labeled as Embed. But isn't the code for YouTube the actual URL? In this case, they should be directed to the URL field (just above the Embed field).
2) The URL to YouTube is incorrect. It currently calls for [http://wwww.youtube.com]. While I support the rights of "w"s to multiply freely, probably not best in a web address. :-)
