It you called MAPIMPORT with an "id statefp10 countyfp10 tractce10 blockce10" then you can put the same ID statement on GINSIDE. That will cause it to return those values. Alternately, you can use GEOID10, which returns all those variables in one variable. It turns out MAPIMPORT must be called with that ID statement or GEOID10. GEOID10 is what it is sorted be so you don't have to have an ID statement for that. Since 'blockce10' is not unique (there is one in many tracts, it many counties) then you cannot use just that.
