I Have No Idea Where I Have Gone Wrong!

Not sure what I have done wrong in my code, but I have checked over it numerous times and still I don't know why the error is saying i am missing an "IN" statement, even though I have included "INNER JOIN" within my code. Any help guys? Thank you.

My initial thought would be that they want you to write this subquery using an "IN" statement - so not an INNER JOIN. You can achieve the same results with an INNER JOIN but the question is asking for the "IN".
