(mostly untested):

function toggleKml(file) {
var kmlCheckbox = document.getElementById(file).checked;
if (kmlArray[file]) { /* don't overwrite kml overlay if it already
exists */
kmlArray[file] = new GGeoXml('http://www.mu130.acres-air.co.uk/
Maps/'> + file + '.kml');
}
if (kmlCheckbox)
map.addOverlay(kmlArray[file]);
else
if (kmlArray[file]) { /* don't remove overlay if it hasn't been
created */
map.removeOverlay(kmlArray[file]);
}
}
