    I'm using http://kung-fu.co.il/ckfa.asp for the map and http://kung-fu.co.il/data.xml for the data location.

    For some reason, clicking on the location point returns NULL instead of the label value. What am I missing?

    It says "Location: I am here" for me. Seems to work fine. Maybe your xml file is being cached by your browser and you are seeing an old version?
