Feed doesn't display the content

Hi there,
Trying to get this nice Plugin to work:

I got this feed (json) : http://www.lokalebasen.dk/lease/api/db_madsen/newest_locations
showing 5 newest objects.

Should show a list with an Address (text) and Photo, wrapped in an URL.

I made this Shortcode
[json src="http://www.lokalebasen.dk/lease/api/db_madsen/newest_locations"] {address}, {url}, {photo_url}[/json]
but it’s only shows the comma’s
What’s wrong here??

Regards!!
