That's the length of the last polyline.
Try this:
var kilometres = 0;
for (var a = 0; a < lines.length; a++) {
// get any line attributes
var colour = lines[a].getAttribute("colour");
var width = parseFloat(lines[a].getAttribute("width"));
// read each point on that line
var points = lines[a].getElementsByTagName("point");
var pts = [];
for (var i = 0; i < points.length; i++) {
pts[i] = new GLatLng(parseFloat(points[i].getAttribute("lat")),
parseFloat(points[i].getAttribute("lng")));
}
var poly = new GPolyline(pts,colour,width);
var kilometers += poly.getLength()/1000;
map.addOverlay(poly);
}
// display total distance
document.getElementById("distance").innerHTML =
"The total distance is " + kilometers +"km.";
Watch out for the subtle change on this line to use += rather than =:
var kilometers += poly.getLength()/1000;
