I’ve done something (not sure what) to my map and now a function that was running is now throwing the following error:
Invalid value for property <travelMode>: undefined line 16 main.js
The last thing I did was add the line:
directionsDisplay.setPanel(document.getElementById("directions"));
So that I can display direction details in a div. Here’s my code for reference:
// This function sets-up and initiates the Google maps interface
function load_map() {

//the start location

center: startLatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// create a JASON object to store map configruation
map = new google.maps.Map(document.getElementById("map"), config);
// intilise the map passing the display divs id and the config
// object
var startMarker = new google.maps.Marker({
position: startLatLng,
map: map
})
startMarker.setIcon('/imgs/startMarker.png');
// create a new marker object for start (passing anonomus JASON
// config object)

Seemed to be working last night but I must have changed something before i stopped working. (which will teach me not to code tired at 2:00 am :-))
Can any of you good people shed some light?
As Requested line 16 reads:

Been trying to work out what it means but cant make much of it, think it may have something to do with the JSON request object but I’m not sure
Your request
should also specify travelMode, eg
http://code.google.com/apis/maps/documentation/javascript/reference.html#DirectionsRequest
