body: <p>I'm developing an application with VB.NET and Google Maps v3 and trying create a map with these properties:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt; 
      $(document).ready(function (){ 
          var sPath ="images/AppIcons/Vehicles/icon05.png,";

              animation: google.maps.Animation.DROP,
              title : "buena"
          });
          var myLatlng = new google.maps.LatLng(0, 0);
          var mapOptions={zoom: 3,center: new google.maps.LatLng(4.590798,-74.084244),mapTypeId: google.maps.MapTypeId.ROADMAP };
          var map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
          var marker = setMarkers(map);
          var infowindow = new google.maps.InfoWindow({Content : '&lt;b&gt;FM3200 - FM3200&lt;/b&gt;&lt;div&gt;&lt;font size=1&gt;&amp;nbsp;&lt;/font&gt;&lt;/div&gt;&lt;div&gt;&lt;u&gt;20/01/2013 04:30:56 p.m. - Voltaje Externo - (Norte)&lt;/u&gt;&lt;/div&gt;Ubicacion Invalida In1:0 In2:0 In3:0 Batext:4.45V Vel:0 Odom:0 Ibutton:0 Oficina Principal Risk, Kmh: 0'});
          if (markers !='') {

              });
          }
      });
      function setMarkers(map,markers) {
          var marker =markers;
          if (marker !='') {
              return marker;
          }
      }&lt;/script&gt;

  <p>When I run this code, this error message appears:</p>
  
  <pre><code>Uncaught TypeError: Cannot read property '__e3_' of undefined main.js:18 
  </code></pre>
  
  <p>How can I solve this error?</p>
