Hi Rossko - thanks for chiming in. Getting at the XML data hasn't been
a problem, because I've been able to create markers from it (if that'
what you mean, I'm not 100% sure by the link you sent). So, yes, my
GMarker creation and listener adding code is already in the same
function as the one as one which draws from the XML source:
function retrieveMarkers {
if request.ready state ==4 etc etc {
get xml info (it does)
if latitude and longitude are returned {
create marker
create listeners
}}}
Then again...
I tried to alter my code, changing var marker = new GMarker(latlng,
markerOptions); to this:
var marker = createMarker(latlng);
map.addOverlay(marker);
...and now the markers don't appear at all. I've left the 'old' line
of code as a comment so you can see what was there before. I'm not
really sure that moving everything to a separate function when all the
variables are already declared in the first function is really going
to help. Would declaring the variable 'marker' outside of the function
help? I doubt it, but I thought I'd put it out there.

Yes, I've been going through 'view source' in Mike's tutorial. It
might address my problem, but in a circumspect way. I think the
versions of the API are the same, too ('2x' or somesuch).
Help! :)
