I found a solution in the forum to show users that are located near me but I dont get it to work.
( 6371 * acos( cos( radians({user map_alias_lat raw}) ) * cos( radians( b.`map_lat` ) ) * cos( radians( b.`map_lng` ) - radians({user map_alias_lng raw}) ) + sin( radians({user map_alias_lat raw}) ) * sin( radians( b.`map_lat` ) ) ) ) < 20
I replaced "map_alias with the alias of my geo field and placed that string into the custom SQL field in user lists module (also tried in maps).
Thank you
