This logic can be nested at any number of levels. This example shows 3 levels: Choose “County” – then choose matching “Cities”, then choose matching “Subdivisions”.
This approach can be applied to any MLS fields.
As this is demo data, there are only 4 cities in ADAMS county. So to see the operation, first select COUNTY (choose “Adams”) – then choose “City” (select “Arvada”) – then select Subdivision (choose “ARLINGTON MEADOWS”). Leave all other fields unselected.
