I have a large dataset and want to apply a parameter that lets me filter by selecting from a drop down of county names. I created a secondary dataset with just the county names. The drop down works perfectly, but it doesn't actually filter anything. I am missing some critical tie between the drop down list (County parameter) and the RES_COUNTY field in the dataset.
Am looking to filter on RES COUNTY by the list of drop down options for COUNTY (added to the dataset exclusively to create a clean drop down). Any ideas?
