[Tutor] 15 puzzle

[Maritza Rodriguez]

Here is what I have for my "15 Puzzle" program.  The "EXIT" button quits the 
game completely.  The "DONE" button prints the messages that I want 
(although I don't know if it will work once I figure out how to Scramble and 
play the game).  I tried to add a definition for "Scramble", but it is not 
working.  Can anyone help me figure out if I am close or just totally way 
off?  Also, I just cannot figure out how to move the buttons to the blank 
spot.
