User blog:JosephCoalSmyth/YoutubePlayer Template

So for about two hours I have been trying to use the Youtube Player Template, and it hasn't been working. I'm pretty sure I've been getting the code right. I even went onto the Cod Wiki and tried it on there. It worked. I'm not sure why I can't get it to work on here. So anyway, I'm asking if anyone can help me with this.
