javascript - KML markers missing on Google Maps API v3: What's wrong? -

i'm new google maps api v3 , have been closely reading documentation.

my map loads fine, it's not displaying placemarks i've set in kml file (http://hepac.ca/wp-content/mapping/wellnessnetworks.kml). kml validates fine @ feedvalidator , displays without issue in google earth, i'm assuming it's problem code below.

the placemarks appearing @ 1 point, must have accidentally deleted crucial code. in advance helping!

  function initialize() {  var mapcenter = new google.maps.latlng(46.36209, -64.73145); var mapoptions = {      zoom: 7,     center: mapcenter,     maptypeid: google.maps.maptypeid.roadmap,    };                  google.maps.visualrefresh = true;    var map = new google.maps.map(document.getelementbyid("map-canvas"),mapoptions);  var opt = { minzoom: 7, maxzoom: 9 }; // sets minimum & maximum zoom level map.setoptions(opt);  var ctalayer = new google.maps.kmllayer({     url: 'http://hepac.ca/wp-content/mapping/wellnessnetworks.kml',     preserveviewport: true, }); ctalayer.setmap(map);  }  google.maps.event.adddomlistener(window, 'load', initialize); 

if want have more 1 placemark in kml file, need in document or folder:

<kml> can contain 0 or 1 feature elements

<document> can contain 0 or more feature elements

<folder> can contain 0 or more feature elements
