Question

You guys have been helping out solving some of my problems with a Google Map lately, and thank you for that.

I am almost done with this - only one problem is left. W

Answer 1

The code I gave you previously listened for the first two clicks, and added a marker for each. The problem is that when you drag the first marker, it's calling the "click" event again - and thus adding another marker at the same location.

Fortunately, the click event lets you know whether an overlay was clicked. So only execute the code that adds a new marker if overlay is null. Note that overlay is not a boolean.

var listener = GEvent.addListener(map, "click", function(overlay, latlng) {
  if (overlay == null) {
    // code to add new marker
  }
});
