Hi, Matthew -- Im going to take a shot at this in my local environment, i believe. Can you point me to the hints belonging to this challenge? I was unable to find them after a 5 minute search.

Thanks Chris

In the following code snippet in type cast checker, turn one of these booleans on to see the hints.

public static boolean HINT_1_ENABLED = false;
  public static boolean HINT_2_ENABLED = false;

The hints will only work in the challenge -- however.
