Question : Looping over google maps v3 markers

Using Google Maps API v3

Basically just trying to display a map with markers from the returned lat/long of my loads query. The markers are being displayed but the on 'clicl' function is only opening the last marker since the name is not unique. How can I fix this so each marker his a unique name and click function?

Answer : Looping over google maps v3 markers

this is how you do it (see attached code).
some of the javascript code is from this google groups thread: http://groups.google.com/group/google-maps-js-api-v3/browse_thread/thread/f40390e4a6ba89e9/25a246d92f93e9ea#25a246d92f93e9ea
