Unfortunately the page you have linked is showing that it doesn’t exist – http://screencast.com/t/KS800DgWZ

If you’re having problems with the shortcode content displaying, it is usually down to broken html, in which case check your html in the text edit screen, rather than the visual display to ensure no other html tags are breaking the code.

Or it could be caused through a conflict with a third party plugin, disable all non-theme required plugins to see if the shortcode renders.
