3,644 PointsQuestion 4 asks me to get a list of all Female customers but I'm told this query doesn't do it:
SELECT s.* FROM Sale AS s INNER JOIN ( SELECT CustomerID FROM Customer WHERE Gender = 'F' ) AS FemaleCustomer ON FemaleCustomer.CustomerID = s.CustomerID;

Treehouse Project ReviewerHi Grant Whiting 👋
Your SQL statement definitely looks valid. I think this is another situation where the back end of this challenge is looking for something specific, or is getting mad with extra things added. In this case, I believe the alias added to all the Sales is what's throwing it off.
This worked for me
SELECT *
FROM Sale
INNER JOIN (SELECT CustomerID FROM Customer WHERE Gender = 'F') AS FemaleCustomers
ON Sale.CustomerID = FemaleCustomers.CustomerID;
