     Probably because the variable `eachKidGetsTen' is not used.
It is given a value, but that value is never therafter consulted.

     (For future reference: When you have a question about an
"error message," it is a good idea to quote the exact text of
the message.  In this instance I imagine there was no text at
all, but still: Some description of the "error message" would
have been a good idea.  As it is, I'm just guessing -- And, as
SH taught us, "It is a capital mistake to theorize before you
have all the evidence."  But since I theorize ante-factually
only because you force me to, the offense is not mine but yours.
Off with your head!)

     If you removed the " marks, I bet it would pacify Eclipse.
