If I am not mistaken, looks like you have a closure issue here.

see the link to see how you resolve closure issue in google maps

This simple code from google will display a marker on a map:

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var myOptions = {
  zoom: 4,
  center: myLatlng,
  mapTypeId: google.maps.MapTypeId.ROADMAP

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

var contentString = '<div id="content">'+
    '<div id="siteNotice">'+
    '<h2 id="firstHeading" class="firstHeading">Uluru</h2>'+
    '<div id="bodyContent">'+
    '<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +
    'sandstone rock formation in the southern part of the '+
    'Northern Territory, central Australia. It lies 335 km (208 mi) '+
    'south west of the nearest large town, Alice Springs; 450 km '+
    '(280 mi) by road. Kata Tjuta and Uluru are the two major '+
    'features of the Uluru - Kata Tjuta National Park. Uluru is '+
    'sacred to the Pitjantjatjara and Yankunytjatjara, the '+
    'Aboriginal people of the area. It has many springs, waterholes, '+
    'rock caves and ancient paintings. Uluru is listed as a World '+
    'Heritage Site.</p>'+
    '<p>Attribution: Uluru, <a href="">'+
    '</a> (last visited June 22, 2009).</p>'+

var infowindow = new google.maps.InfoWindow({
    content: contentString

var marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    title:"Uluru (Ayers Rock)"

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