title: Google Maps v3,  error message "Google is undefined"
body: <p>I am getting errors on my site just trying to implement the basic "Hello world" application:</p>
  
  <pre><code>&lt;div id="map"&gt;&lt;/div&gt; 
  
  &lt;script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"&gt;&lt;/script&gt;
  
  $(document).ready(function () {
      map = new google.maps.Map(document.getElementById("map"), myOptions);
  });
  </code></pre>
