function drawCountyBorder()
{
                        var polyline = new GPolyline([
                                    new GLatLng(53.1000 +08.8000),
                                    new GLatLng(53.4000 +08.9000),
                                    new GLatLng(53.6000 +08.6000),
                                    new GLatLng(53.8000 +08.3000),
                                                     ])
}
map.addOverlay(polyline);

Warum ist das addOverlay ausserhalb der Funktion?
