What I am missing here? Why is not selecting?
Challenge Task 2 of 5 In a car database there is a Make table with columns, MakeID and MakeName, a Model table with columns, ModelID, MakeID and ModelName and a Car table with columns, CarID, ModelID, VIN, ModelYear and StickerPrice. For all cars in the database, show Make Name, Model Name, VIN and Sticker Price from the Model and Car tables in one result set.
Bummer! Your query didn't select the MakeName, ModelName, VIN and StickerPrice!
➢ SELECT Make.MakeName, Model.ModelName, Car.CarID, Car.ModelID, Car.VIN, Car.ModelYear, Car.StickerPrice FROM Make INNER JOIN Model ON Make.MakeID = Model.MakeID INNER JOIN Car ON Car.ModelID = Model.ModelID;

You might be returning the wrong number of columns.
The challenge asked you to select 4 things, but your SELECT has 7 items
