Removing KML overlay from Google Maps

I have a reset button that I want to reset the map (including removing overlays) when clicked.

I've been reading around and apparently the way you remove KML overlays is by;

  1. Declaring your kml variable as a global variable

    var ctaLayer = new google.maps.KmlLayer(null);

  2. These are the lines that cause the kml file to overlay on google maps

   var ctaLayer = new google.maps.KmlLayer(kmlFile);
   ctaLayer.setMap(map);

  1. And then call setMap(null) to remove the overlay.

    ctaLayer.setMap(null);

However, this does not seem to be working. I don't get any errors so I'm guessing I'm missing something? I'd appreciate any advice on getting this to work.

layer.setMap(null) is correct, so you must be doing something else wrong. Please post code. – ScottE

Remove the var from in front of the second var ctaLayer (the one that makes it local to the function).
