Question

Hi everyone,

I'm making a google map with markers of our company's customers,so that the sales people can make an easy travel guide. However i got alot of markers so i need to cluster them to load them properly.Now i found a few sites that said that markerclusterer was the fastest of the all however if i try to implement it it doesn't work (i'm not good at programming :( ) however maybe someone here does know what i'm doing wrong here is the code i'm using. getting the markers out of the .xml file also found these 2 websites however even with this help i can't figure out what i'm doing wrong
