Trying to set google maps marker using array

Question

I'm fiddling with the maps v3 API and I'm using some examples from the web to try and get some differing markers. I can't seem to figure out why it's not working. I'm going for a similar map as this one - the idea is to filter out community members by the game they play/own......

http://googlemaps.googlermania.com/google_maps_api_v3/en/map_example_sidebar2.html

So I've created my array very similar with just two entries:

var stationList = [
    {"latlng":[231.015,126.431],name:"membername1", battlefield4 : 1, warframe : 1, Ghosts : 1, Killzone: 0},
    {"latlng":[234.004,134.999],name:"membername2", battlefield4 : 1, warframe : 1, Ghosts : 1, Killzone: 1},
  ];

And the block code I'm editing is:

    var bounds = new google.maps.LatLngBounds();
    var station, latlng;
    var image = './img/member.png'

    for ( i = 0; i < stationList.length; i++) {
      station = stationList[i];
      latlng = new google.maps.LatLng(station.latlng[0], station.latlng[1]);
      bounds.extend(latlng);

      var marker = createMarker({
        map : mapCanvas,
        position : latlng,
        others : station,
        icon: image
      });

At the moment this assigns a default icon to everyone and works well, but there are roles within the community that I'd like to represent differently. What I did was add an entry to the array as follows:

var stationList = [
    {"latlng":[51.515,-0.101],name:"membername1", battlefield4 : 1, warframe : 1, Ghosts : 1, Killzone: 0, image: "./img/founder.png"},
    {"latlng":[51.678,-0.205],name:"membername2", battlefield4 : 1, warframe : 1, Ghosts : 1, Killzone: 1, image: "./img/founder.png"},
  ];

And then edited the marker block as follows:

 var bounds = new google.maps.LatLngBounds();
    var station, latlng;
    var image;

    for ( i = 0; i < stationList.length; i++) {
      station = stationList[i];
      latlng = new google.maps.LatLng(station.latlng[0], station.latlng[1]);
      bounds.extend(latlng);
      image = station.image;
      var marker = createMarker({
        map : mapCanvas,
        position : latlng,
        others : station,
        icon: image
      });

But it just seems to bomb the whole page out. I figure I'm not addressing the array properly or it's something to do with quotation marks etc. Any tips?

Thanks
