I am trying to write a municipal tax collection program. I have a table for school taxes and a second table for municipal taxes. The property info in both tables is identical, and the tax info is different, although not all records may be in both tables. I am writng a query for a report that shows what taxes have not been paid, based on whether the "date paid" field is or is not null. When I run the query, some records show up 5 or 6 times, which is not a good thing.
