prototype map method

Ok...so looking at like 340...

I have the function that executes the map method and it passes the first test, but on the second test the index that is passed and my code is returning not a number.

Callbacks take the index as the second value in the callback, so I'm confused why my code isn't working. In this instance, "i" is the index. Any ideas what I am missing here?
