It kind of depends on what you mean by dups.
It could be as simple as changing the query by adding the Distinct predicate.
In query design view, set the queries Unique Values property to yes.
== open query in design view
== select View: Properties from the menu
== Click on a blank area of the top section that displays the tables
== Change Unique Values to Yes
IN SQL view, add the word DISTINCT after the word SELECT
SELECT DISTINCT SomeField
FROM SomeTable
ORDER BY SomeField
