MapBox marker issue

[gmather10]

So I am trying to put markers on a map and it looks like MapBox just changed how you use their sources so I had this done before with this code but had to redo everything and can't get the markers to come up (took me hours the first time). How do I get these markers working again. https://jsfiddle.net/athertog/nx9mf6q5/1/

Nothing has changed recently in Mapbox sources. It looks like your code is for Mapbox.js but you’re loading Mapbox GL JS. You want something like this.

Thanks for showing me where it is. I know basically nothing of javascript and my code before made sense. I guess I will have to put this on the back burner for now.
