Please read the posting guidelines:
http://groups.google.com/group/google-maps-js-api-v3/browse_frm/thread/2b3f101fd509919e

The code that you posted to the group:
1. is mangled
2. can't be run in a debugger
3. doesn't have any function marked in red

Hi Larry,

Don't know what you mean with regards to 'mangled', have no idea what debugger your using and the text is in red in my post?

Here is a link to the live page:mySample

Kind regards Paul.

I get obvious javascript errors on that link.

Both your map and markers variables are local to your load function.
They need to be global to be accessible to javascript run from html.

I appreciate you taking time to help Larry, im new at this which must be frustrating to people like yourself.

Ive made both map and markers global as per the previous link and get same lack of results.

Regarding js errors whats best to debug in as a newbie, i have firebug but not sure how to debug js with it.

Paul.

I still get an error:
Line: 78
Error: 'map.markers' is null or not an object

I think that should be "markers" not map.markers.

Look at the Error Console (Ctrl-J or Ctrl-Shift-J I don't remember or
Tools:Error Console)

Yes I've spotted that and amended it but still get:

markers[i].setVisible is not a function

in the console?

markers is an array of XML DOM elements, they don't have .setVisible
methods.

You need to create an array of the google.maps.Marker objects you
create if you want to affect them after they have been created.

See:
http://www.geocodezip.com/v3_MW_example_map3.html
for an example that does that.

It seems to work as I would expect, and I don't get errors doing the
things I did.

Is that what you are asking?
