Hey Mary Kissiedu, the error message says "Bummer: Hmm, the items don't seem to be sorted". The issue isn't the sort it's that the parent and the local methods both append the new item to the slots list resulting in double counting. Since the parent method had the append, it can be removed from the local method.

Post back if you need more help. Good luck!!
