You need to keep a _unique_ reference to each overlay so you can
remove it. I usually use an associative array, something like
(totally untested):
var kmlArray = [];
function toggleKml(file) {
var kmlCheckbox = document.getElementById(file).checked;
kmlArray[file] = new GGeoXml('http://www.mu130.acres-air.co.uk/Maps/'
+ file + '.kml');
if (kmlCheckbox)
map.addOverlay(kmlArray[file]);
else
map.removeOverlay(kmlArray[file]);
}
