It looks like you are trying to provide the full answer but that is not allowed on the forum.
Instead it is best to help the OP out with hints so they can arrive at the solution on their own.

In this case, this post is over 4 months old.
So it is safe to say that the person has moved on from this challenge.

It is best to reply to more recent conversations.

Thanks for understanding.
