title: Why this jsfiddle wont run?
body: <p>This is probably a stupid mistake, but I'm new to jsFiddle, and I can't run this piece of code:
  <a href="http://jsfiddle.net/rnG4n/" rel="nofollow">my fiddle</a></p>
  
  <p>The code should put either <code>OK</code> or <code>not ok</code> in the .output div. It doesn't do it. Thanks</p>
