Why clustering does not work? (google maps API V3)

Question

I just started using the version 3 of the google maps api, and i am making a simple implementation of clustering, but i cant make it work. Maybe you can see where is my error, and help me making it work:

var map;

function runmap() {
        //Prepare cordinates
        var myLatlng = new google.maps.LatLng(-34.397, 150.644);
        //Prepare other options
        var myOptions = {
        zoom: 3,
        center: myLatlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
        //,disableDefaultUI: true//Uncoment to disable map controls
        };

        //Prepare map using de destination id(in the html page) and the options
        map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);

        //Adding markers(Search marker options for more options)
         var marker = new google.maps.Marker({
         position: myLatlng, 
         map: map,
         title:"Zdravo",
         icon:"djole.png"//Change the icon of the marker
         });

        var marker2 = new google.maps.Marker({
         position: new google.maps.LatLng(-34.597, 150.744), 
         map: map,
         title:"Zdravo",
         icon:"djole.png"//Change the icon of the marker
         });

         var marker3 = new google.maps.Marker({
         position: new google.maps.LatLng(-34.290, 150.444), 
         map: map,
         title:"Zdravo",
         icon:"djole.png"//Change the icon of the marker
         });


        var markers = [];
    markers.push(marker);
    markers.push(marker2);
    markers.push(marker3);
    var markerCluster = new MarkerClusterer(map, markers);
    }

Update This is the error i see:

Answer 1

You need the MarkerClusterer or MarkerClustererPlus for Google API version 3. It looks like you are using MarkerClusterer for Google Maps API version 2.
