Sure enough, once I reach out for help, I find my own solution:
My issue was that I instantiated (right word?):
var map;
within the initialize function, and not globally, so it wasn't defined
for the moveToDarwin function.
var map;
function initialize() {
var latlng = new google.maps.LatLng(centerLatitude,
centerLongitude);
var myOptions = {
zoom: startZoom,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new
google.maps.Map(document.getElementById("map_canvas"),
myOptions);
.....
Thanks anyway for not rejecting my noobie question.
Until next time!
