HI
Im sure this is an easy one for someone who knows thier javascript
I am trying to adapt an example to use a drop down box to enable the
user to choose driving or walking directions. I am close to doing
this, so really frustrated being new to javascript. Please could
someone help me with this and put me out of my misery and look at the
code below. Have marked the crucial areas with **********
Help will be so appreciated
Thanks in advance
Lee
<script type="text/javascript">
var map;
var gdir;
var geocoder = null;
var addressMarker;
var walkingDriving ={}
function initialize() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map_canvas"));
gdir = new GDirections(map, document.getElementById
("directions"));
GEvent.addListener(gdir, "load", onGDirectionsLoad);
GEvent.addListener(gdir, "error", handleErrors);
setDirections("San Francisco", "Mountain View", "en_US");
}
}
// ************************************************* here
function setDirections(fromAddress, toAddress, locale, travelMode) {
if(document.form.travelMode.selectedIndex == 0){
walkingDriving.travelMode=G_TRAVEL_MODE_WALKING;}
gdir.load("from: " + fromAddress + " to: " + toAddress,
{ "locale": locale, "travelMode": travelMode });
}
function handleErrors(){
if (gdir.getStatus().code == G_GEO_UNKNOWN_ADDRESS)
alert("No corresponding geographic location could be found for
one of the specified addresses. This may be due to the fact that the
address is relatively new, or it may be incorrect.\nError code: " +
gdir.getStatus().code);
else if (gdir.getStatus().code == G_GEO_SERVER_ERROR)
alert("A geocoding or directions request could not be
successfully processed, yet the exact reason for the failure is not
known.\n Error code: " + gdir.getStatus().code);
else if (gdir.getStatus().code == G_GEO_MISSING_QUERY)
alert("The HTTP q parameter was either missing or had no value.

as input. For directions requests, this means that no query was
specified in the input.\n Error code: " + gdir.getStatus().code);

Doc bug... this is either not defined, or Doc is wrong
// alert("The geocode for the given address or the route for the

else if (gdir.getStatus().code == G_GEO_BAD_KEY)
alert("The given key is either invalid or does not match the

function onGDirectionsLoad(){
// Use this function to access information about the latest load

// results.
// e.g.
// document.getElementById("getStatus").innerHTML =
