What makes a line a line in a chunk expression?

[Len Morgan]

Jim,

This works on my machine but as Sarah pointed out to me, it's actually 
pointless since they should NEVER be different (i.e., it should never 
pick something that is not on the list of options so why check?  What I 
really wanted to do was see if a CARD with that name existed (something 
like "if pChoice is among the cards of this stack..." which doesn't work 
because apparently, "the cards of this stack" is not a valid command.
