That code creates a new GPoygon that's similar to the original one and
tries to remove that from the map, which fails because it was never
addOverlay()ed.
What you have to do is keep global references to all your GPolygons.
var gpolygons = []; // Global
...
map.addOverlay(fall);
gpolygons[a] = fall;
...
else {
for (var a = 0; a < fallow.length; a++) {
if (gpolygons[a]) {
map.removeOverlay(gpolygons[a]);
gpolygons[a] = false;
}
}
}
[The if (gpolygons[a]) and gpolygons[a] = false; are defensive
coding, to prevent any possibility of calling removeOverlay twice on the
same polygon.]
