You have a code to a YouTube video on there. There's a code on here where you can embed the video, which is what I thought you were doing. I can't do it myself for several days but it worked on the preview (but wouldn't let me post it).
LATER EDIT: never mind, I saw another post that looks just like this one. It looks like it has a messed-up link, but it's due to the deal where no one other than an admin can view it.
