what wrong ?

you have forgot create google maps object add map on page.

//var map; var mapoptions = { center: new google.maps.latlng(start[0], start[1]), zoom: 3,         maptypeid: google.maps.maptypeid.roadmap }; // create object var map = new google.maps.map(document.getelementbyid("map_canvas"), mapoptions);

jsfiddle + create map object @ google api v3 documentation
