I am having trouble with the following code:

function initialize() {
            //myLatLng = new google.maps.LatLng(37.422104808,-122.0838851);

            var myOptions = {
                zoom: 18,
                center: new google.maps.LatLng(42.564613,-70.809087),
                // zoom: 5,
                // center: myLatlng,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            map = new google.maps.Map(document.getElementById("map_canvas"),
                  myOptions);

   geoXml = new geoXML3.parser({
                map: map,
                singleInfoWindow: true,
                afterParse: useTheData
            });
            geoXml.parse('ActivityStatus_Producing_labels.kml');
        };
function kmlClick(marker) {
  google.maps.event.trigger(geoXml.docs[0].markers[marker],"click");
}

function useTheData(doc){
  // Geodata handling goes here, using JSON properties of the doc object
 var sidebarHtml = "<table>";
 for (var i = 0; i < doc[0].markers.length; i++) {
 // console.log(doc[0].markers[i].title);
sidebarHtml += '<tr><td><a     href="javascript:kmlClick('+i+');">'+doc[0].placemarks[i].name+'</a></td></tr>';
  }

I am getting an error that doc[0].markers.length cannot get the length from a null or non existent variable depending on which browser I use.

In this website: http://thoughtfi.com/geoxmlpractice/practiceIMR2.html I can get it to run in Chrome but not IE

This website works in IE and Chrome and has almost the same code: http://www.geocodezip.com/geoxml3_test/v3_geoxml3_us_states_kml_test.html

How can I get my site to work? I’m guessing it’s not parsing the kml file in time or the server/browser is too slow to parse the kml?

    It seems to be the kml file. IE doesn’t believe it is valid xml. Neither does feedvalidator:
    http://www.feedvalidator.org/check.cgi?url=http%3A%2F%2Fthoughtfi.com%2Fgeoxmlpractice%2FActivityStatus_Producing_labels.kml#l675

    If I fix the invalid xml (and the character encoding the xml file reports), it works for me:

    Here is another example displaying the “fixed” kml

    You can also see what Google Maps thinks of your kml:

    http://thoughtfi.com/geoxml… could not be displayed because it is not a valid KML or KMZ file.
