I am a newbie to KML and the Google Earth API.

I have created a new website featuring Shropshire Sundials, "www.shropshiredials.net" using KML 
to make the sundial placemarks and balloons with HTML

Here is part of the €KML file:

<?xml version='1.0' encoding='utf-8'?>
<kml xmlns='http://www.opengis.net/kml/2.2'>

		<text>                   <!-- eliminates the driving directions -->

Note that the "#aerial;flyto" line allows the viewer to fly back to the start placemark , id = "aerial"

Link to www.shropshiredials.net/GESS.kmz  This works OK  So far, so good. Now I want to use the API's KMLNetworkLink for the viewer to go directly to my home webpage. Here is a snippe of the code:

   function initCallback(pluginInstance) {
      ge = pluginInstance;
      ge.getWindow().setVisibility(true);
		// Earth is ready, we can add features  to it
	  addKMLFromUrl('http://www.shropshiredials.net/GESS.kmz');
	  }

	  function addKMLFromUrl(kmlUrl) {
      var link = ge.createLink('');
      link.setHref(kmlUrl);

      var networkLink = ge.createNetworkLink('');
      networkLink.setLink(link);
      networkLink.setFlyToView(true);

      ge.getFeatures().appendChild(networkLink);
    }

    function failureCallback(errorCode) {
    }
  </script>
</head>


The original KML is the same but now the viewer can not "flyto" back to the start placemark.

The problem is, I think, related to the "aerial" identifier in the KML file but I can't work it out!


Here are the two links:

Your help would be very welcome.
