title: Javascript error "MyIdentifier is not defined"
body: <p>I broke the google map <a href="http://www.comehike.com/hikes/search_hikes.php?all=yes&amp;when=f&amp;redirect=yes" rel="nofollow">on this page</a>, and it is giving me an error:</p>
  
  <blockquote>
    <p>placeHikesMarkers is not defined</p>
  </blockquote>
  
  <p>What is the best way to debug JS in this case?</p>
