Day 16: Keyboard does not respond to input

Hi! I'm having an issue with the code for day 16 where my keyboard won't respond to input. The Xbox pad works as expected and I've gone through the video and double checked to make sure I did everything exactly as Casey has.

Here's my code in CALLBACK WinMain:

while (GlobalRunning)
      {
          game_controller_input *KeyboardController = &NewInput->Controllers[0];
          // TODO: Zeroing macro
          game_controller_input ZeroController = {};
          *KeyboardController = ZeroController;

          Win32ProcessPendingMessages(KeyboardController);

          // TODO: Should we poll this more frequently?
          DWORD MaxControllerCount = XUSER_MAX_COUNT;
          if (MaxControllerCount > ArrayCount(NewInput->Controllers))
          {
              MaxControllerCount = ArrayCount(NewInput->Controllers);
          }

          for (DWORD ControllerIndex = 1;
          ControllerIndex < MaxControllerCount;
          ++ControllerIndex)
          {
              game_controller_input*OldController=&OldInput>Controllers[ControllerIndex];
game_controller_input *NewController = &NewInput->Controllers[ControllerIndex];

...

Changing

1 2	game_controller_input OldController = &OldInput->Controllers[ControllerIndex]; game_controller_input NewController = &NewInput->Controllers[ControllerIndex];

1 2	game_controller_input OldController = &OldInput->Controllers[ControllerIndex + 1]; game_controller_input NewController = &NewInput->Controllers[ControllerIndex + 1];

fixes the issue but Casey doesn't do this in his code. What's the deal? I mean, so, yes I fixed it but why does it work fine on Casey's machine?
