it looks right...a few things to check:
1. did you add 'LOCATION' as the dimension for the map ?
2. after #1, did you drag IMPORTO into the same map ? when you do this it should prompt you to select sum,avg, min etc...
3. then just make sure the background / show property on the right is set to 'ON'
I would suggest doing steps 1-3 after dragging in a brand new map object onto the dashboard. its trickier to change an existing map.
