Panel Not Working

Panel Not Working

I've created a very simple page, with a panel on it. I've compared it with other working examples of the panel, and I can't see any noticeable differences. Really need a fresh pair of eye of eyes on this. Please check out the code here... 


The text 'This is where the panel should be' is what should be appearing in the panel... but instead its appearing on the page instead and the panel does not open.  Any help would be much appreciated. Thanks in advance,
