Error in script

Hi, Please help with correct script. Mine is with error: Bummer: The subquery doesn't return all ModelIDs for cars with the sticker price greater than 30000.

SELECT ModelName, StickerPrice FROM MODEL JOIN CAR ON MODEL.ModelID = CAR.ModelID WHERE StickerPrice IN (SELECT StickerPrice FROM CAR WHERE StickerPrice >30000)

Here's a few hints:

  • the challenge only asks you to "list all the Model Names"
  • use the subquery to identify models with the right price
  • use WHERE and IN to filter using the subquery
  • you won't need to JOIN tables for this
