domanda semplice semplice...

perchè riesco a far visualizzare la mappa ma non i marcatori? ;(

codice:

<div id="contatori"><script>

$.cookie("alt", $(window).height()-25,{path: '/'});

$.cookie("larg", $(window).width(),{path: '/'});

</script>

</div><link href="include/css/main.css" rel="stylesheet" type="text/css" />

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>

<script type="text/javascript"> 

  function initialize() {

    var myLatlng = new google.maps.LatLng(45.5615912,12.2981034);

    var myOptions = {

      zoom: 8,

      center: myLatlng,

      mapTypeId: google.maps.MapTypeId.ROADMAP

    }

    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

  }



var pos0 = new google.maps.LatLng(45.6662855,12.2420720);var marker0 = new google.maps.Marker({

        position: pos0, 

        map: map, 

        title:"Store 1"

    });

google.maps.event.addListener(marker0, 'click', function() {

      map.set_center(pos0);

      map.set_zoom(8);

    });var pos1 = new google.maps.LatLng(45.5615912,12.2981034);var marker1 = new google.maps.Marker({

        position: pos1, 

        map: map, 

        title:"Store 1"

    });

google.maps.event.addListener(marker1, 'click', function() {

      map.set_center(pos1);

      map.set_zoom(8);

    });  

</script> 



<body style="padding:0px; margin:0px" onload="initialize()">

<div id="map_canvas" style="width:100%; height:100%"></div>

</body>
