Location Distance/Proximity: Origin from views nid argument

I am developing a Drupal 7/Omega 4 (panels & views) estate agent app. For each individual property I need to include distance/proximity to their local schools. With that in mind, I installed (among others) following modules: Location, Node Location, Location CCK, Location Taxonomy and Location Search.

I constructed a view (titled distance_sec_school; it is included on the individual property page), which should calculate and display the distance.

I entered latitude/longitude of local schools into 10 original content pieces of secondary schools content type. Next I entered zip/post codes and latitude/longitude details of each property and all I need now is to display the list of all local schools within 3 miles radius of viewed property (and proximity of those schools to the current property).

Now, if at fields -> Location: Distance/Proximity ->Settings I choose 'Static Latitude/Longitude' option from the drop-down menu and enter the values manually (green frame boxes on the screenshot) it gives me the proximity to the schools, which is cool, but not what I need.

I need to dynamically fetch the Latitude/Longitude values from the current (viewed) propertiy, and use them instead of the above mentioned Static values.

I tried 'Node's Lattitude/Longitude from views nid argument' - (I should add that I am using "Contextual filter: Content: Nid" and WHEN THE FILTER IS NOT AVAILABLE - I provide default value: Content ID from URL.)

Finally, at the bottom of the configure screens I have 2 'Location to use' options - 'Node Location' or 'CCK location' but whichever I use I got a blank screen.

Does anybody have an idea what am I doing wrong here? Please take a look at the screenshot of my view and its various Settings. I am stuck on this one for 2 weeks now and would really apreciate any ideas.
Thank you for your time,
