Thread:Extension talk:Semantic Maps/Semantic Maps not working?

Hi, I'd really appreciate if someone could help me out here. I wanted to use SM for showing the locations of all the database users around the world. The "Current residence city" is a property I have installed. The code I use is:

However I dont see any map in the produced page!! To be clear, the users havent input their cities as coordinates, but by names. Using geocoding, I can get each one of their cities individually like this:

But I cannot get their locations aggregated in SMW query.

I wonder what could be wrong?

Thanks!
