Trying this one again and seeing if I can be clearer through more screen prints.
I tried to make a portal filter by two dimensions: 1) County (which is a single-entry field and works fine) and 2) Building Type (which is a checkbox or multi-entry field and does not work. See attached for field calcs, etc.
(The check-box filter is the problem. When I only link the relationship from County to the Countyfilter, it works fine. When I add the buildingType checkbox field, it does not (see example in screen print where I select "Land" and it doesn't filter out the other selections). (P.S. - I even tried to simplify by linking the PFbuildingtype field directly to the global field (g_FilterBuildingType) instead of the calc field (c_FilterBuildingType), and it still didn't work. Any ideas?
