Javascript isn't my forte but I can get by by trying to read the code and just figuring it out from there, but I can't seem to get this working.

I made a fiddle here, https://jsfiddle.net/aed9ajr7/1/

What I am trying to do is add more markers to that map and from what I've read it should be as simply as adding this for it to add more markers:

var locations = [
    ['Bondi Beach', 29.461739, -81.251943, 4],
    ['Coogee Beach', 29.462075, -81.253735, 5],
    ['Cronulla Beach', 29.461235, -81.251922, 3],
    ['Manly Beach', 29.461664, -81.254389, 2],
    ['Maroubra Beach', 29.462066, -81.251192, 1]
];

These are just some random locations that are near the center of the map on jsfiddle.

I think it conflicts somewhere since the jsfiddle example uses a custom marker, or maybe I just keep forgetting to add some extra code to make it work. ¯\(°_o)/¯

Could someone help me out and tell me where I'm going wrong?

Thank you in advance.

edit: Solved it myself

I'll leave the post up in case anyone else needs it.

I added:

var marker2 = new google.maps.Marker({
    position: new google.maps.LatLng(newlatitude, newlongitude),
    map: map,
    visible: true,
    icon: marker_url,
});

after var marker = new google.maps.Marker({.......}); and that did the trick.

(change lat & lon to the ones you want added)
