Thread:Talk:Semantic Maps/Advice with Semantic Maps

I'm trying to set up a wiki linked to site in my village (http://hhg.clusteragency.co.uk/index.php) - the combination of MediaWiki, SMW, Maps and Semantic Maps seems ideal if only I can make it work

A typical page has this code:

which calls a template:

note I'm using two properties as I can't get either to work.

The homepage which is running the query:

So the table shows that both properties are being pulled in, but the map does not display any markers. The same thing happens with KML type - it's like Semantic Maps is looking for a different property name. I've trawled through all the documentation and examples I can find and tried everything I can think of.

Versions installed should all be current: MediaWiki: 1.21.1, Semantic Maps (Version 3.0 alpha), Semantic MediaWiki (Version 1.9 alpha), Maps (Version 3.0 alpha)

Any suggestions or advice would be HUGELY appreciated.
