Task 1 challenge help

The question: In a car database there is a Model table with columns, ModelID, MakeID and ModelName and a Car table with columns, CarID, ModelID, VIN, ModelYear and StickerPrice.

Use a subquery along with IN to list all the Model Names with a Sticker Price greater than $30000

My code: SELECT modelid FROM model WHERE modelid IN (SELECT stickerprice FROM car WHERE stickerprice > 30000)

Thanks!

Since modelid IN is trying to match modelid's your subquery should be retrieving modelid's.
