At Wikipedia:Ōnawe Peninsula, I can't display a marker, even if I directly copy the Exploratorium example and just edit its co-ordinates. AM I just doing something foolish? I'm trying to follow the directions. HLHJ (talk) 19:05, 7 March 2020 (UTC)

I corrected it for you -- the marker did appear but somewhere near the top of the map.
Coordinates section should be "long,lat" and not "lat,long" --- ie. "coordinates": [ 172.9293, -43.7909] },
I also add a # sign on the hex color for the marker - "marker-color": "#0050d0" -- Not sure if that matters here as I work on a different wiki.
Hope that helps - Cheers! ~~~~
A belated thank you, @Matroc. I really had done something foolish! HLHJ (talk) 14:37, 2 August 2020 (UTC)
@HLHJ You are welcome! Just a minor thing - you would be surprised how many people put coordinates as lat,long - not foolish - all the best!
