Move the initialization of the markerclusterer inside the callback
function after you have inserted the returned data in the array (as I
said above):
...
// put the assembled side_bar_html contents into the
side_bar div
document.getElementById("side_bar").innerHTML =
side_bar_html;
markerCluster = new MarkerClusterer(map, gmarkers);
GLog.write("loaded "+markerCluster.getTotalMarkers()+"
markers");
