I am wanting to use a different marker-file based on a value returned via SQL in cartodb. I am wanting todo something like
Where the value in [icon] is a full URL to a PNG image. When I do the above there is no error displayed, but there is no marker displayed on the map. If I use the below then the marker is displayed.
The value returned by [icon] is identical to this full URL. Any suggustions on how to use SQL values to define marker-file urls?
