Was I supposed to put something else in the index.html? He talks about putting something in between line 10 and 12 but he never does in the video?

Hi Melissa,

I haven't watched the video, but I did copy your code and run it in my browser, Google Chrome. Chrome's debugger (open it with hotkey ctrl + shift + j on Windows, or command + option + j on Mac) reported an error on line 20: Uncaught SyntaxError: Unexpected token =

I believe this was due to a syntax error in your for loop: for (var = i; i < arr.length; i += 1)

See the problem? :) var = i will cause the debugger to throw an error, so I just changed it to var i = 0; and it worked like a charm.

Hopefully that helps, and let me know if you have any other questions!
