Here are a few hints:

  • This challenge is about variable scope, it does not involve try and catch
  • A variable should be defined in the outermost scope it is used in.
  • A variable should be defined before it is assigned (or at the same time).
  • A variable can be assigned many times, but should only be defined once.

It's more simple then we think it is. It took me so long to figure this one out, and i thought 'Steven Parker' was wrong, but yeah he is pretty much right.

Pay attention to his tip about where to assign the variable and read what the console error tells you. I was pretty much redefining variables multiple times.
