This code has a number of intentional errors.

This challenge is different from most in that regard. But here's a few hints:

  • a variable must be declared before it can be assigned (or at the same time as the first assignment)
  • a variable can only be declared one time
  • a variable can be assigned multiple times
  • a variable should be declared in the outermost scope in which it is used

Look for places in the code where one or more of these rules is violated. You should find at least 3 errors involving 2 different variables.
