Assuming you are working on task 1, the instructions say: *"Use a subquery along with IN to list all the Model Names with a Sticker Price greater than $30000".

So you were very close, all you need to change is which column you select (instead of all of them):

SELECT ModelName FROM Model WHERE ModelID IN (SELECT ModelID FROM Car WHERE StickerPrice > 30000);

Thank you very much indeed and for the explanation, as somebody told me that it would better to erase all column!
