Dear Edward,

I think I have discovered the problem. In my code, I did a pop(@in) just to remove the newline that occurs when the user types in the letters. This was accidentally left in your code. If you comment out line 41, everything should work fine!

I hope this helps - let me know how it turns out!

Best

Update: The finally (maybe :-) revised code (that should do everything correctly) can be found here.

Another Update! Hehe - ok... lets hope this hits the mark: Code is here

YA-Update: The correct and final code is in the above post. Yay.

Be well,
  -Adam
