A start would be to remove these two lines from your showAddress function: map.addOverlay(marker); marker.openInfoWindowHtml(address); The first adds the overlay (the marker) to the map, the second opens the infowindow on that marker (which once you remove that line, won't exist). If you still want the infoWindow, you will have to use map.openInfoWindow... functions (see the documentation, the syntax is slightly different). -- Larry > > thank you > > On Jan 26, 5:36 pm, Rossko <[email protected]> wrote: > > > > > >http://www.charitywater.org/projects/map_googlemaps.php > > > Your KML doesn't show up in FF2, I don't know why but the > > filehttp://www.charitywater.org/map/wells.kml > > fails validation inhttp://kmlvalidator.com/validate.htm > > > > The goal here is to allow a user to search and locate a project based > > > on it's GPS coordinates.
