Querying Relational Databases - challenge task 3

My query

SELECT SalesRep.FirstName, SalesRep.LastName, SUM(Sale.SaleAmount) FROM Sale INNER JOIN SalesRep ON SalesRep.SalesRepID = Sale.SalesRepID GROUP BY SalesRep.SalesRepID

returns the error, something like, "your query didn't return FirstName, LastName, SaleAmount."

what am I overlooking that's wrong?

The challenge is asking for a query that will return these values on each sale. So you won't need the aggregate function SUM, or any "GROUP BY" clause.
