Hello Roxanne, Sorry you didn't get a timely reply. Hopefully this still helps.

The tables that you should be using are Car and Model. In your query you have SELECT Make.MakeName and FROM Make INNER JOIN Model ON Make.MakeID. Make is a column name in the Model table.

You are only joining 2 tables in this challenge "Model and Car"

Please write back if you need further explanation. KEEP CODING! :)
