Arrays and Recursion: Scrabble with Revolution

[John Stone]

Hi, I just downloaded the scrabble stack from the rev news letter
and on running it I got the message 

     	executing at 9:42:52 AM
Type	Function: error in function handler
Object	card id 1002
Line	return permuteSequence(pAvailableLetters)
Hint	permuteSequence

so i made the function permuteSequence 'non' private then it works fine, 
don't know why this is as I have lots to learn, any help on why this fixes
the prob will be appreciated
Thanks for this stack, I am certainly going to learn lots from it
