Thought I was doing pretty good adding the Facebook Comments box to a product page, but I seem to have hit a snag trying to figure out what I can use for the

<meta property="fb:app_id" content="{YOUR_APPLICATION_ID}"/>

I'm needing to be able to be able to moderate the comments as outline on the Comments plug-in page

If you have specified your app id as the admin, you can moderate all your plugins at http://developers.facebook.com/tools/comments.
If I login to Facebook as the admin, I can click that link and it has an app id. I've tried using it but the "linter" doesn't like it. Do I have to create an app just to be able to moderate the comments? What am I missing?

Thanks,
Leslie
