I have duplicates returned in the following query. Is it possible to refine
this query to remove the duplicates or prevent duplicates from occuring
without disrupting the query?

WHERE (([ListingsID] Is Null Or [tblListings].[ListingsID]=[ListingsID]));
 
Have you taken a look at the "DISTINCT predicate" - (see
Access help for more information)
