There is a discussion and example of TOP N here

I tried that. I get a syntax error. My SQL skills are limited. Here is what I have. Any ideas on what is wrong?

SELECT [Q 3: Group Transactions by Employee].[Employee Number], [Q 3: Group Transactions by Employee].[Last Name], [Q 3: Group Transactions by Employee].[First Name], [Q 3: Group Transactions by Employee].[Hierarchy 4], [Q 3: Group Transactions by Employee].[Hierarchy 5], [Q 3: Group Transactions by Employee].[Month End], [Q 3: Group Transactions by Employee].[SumOfNet Cost]
FROM [Q 3: Group Transactions by Employee]
WHERE [Q 3: Group Transactions by Employee].[SumOfNet Cost] IN
(SELECT TOP 3 SumOfNet Cost
FROM Q 3: Group Transactions by Employee AS Dupe
WHERE Dupe.Month End = Q 3: Group Transactions by Employee.Month End
ORDER BY Dupe.Month End DESC, Dupe.SumOfNet Cost DESC)
ORDER BY Q 3: Group Transactions by Employee.Month End, Q 3: Group Transactions by Employee.Month End, Q 3: Group Transactions by Employee.SumOfNet Cost;
