Chris,
the problem is here ^^^^^^^^^^^^
   if [ $ANSWER = "yes" -o $ANSWER = "YES" ]
would likely work.
Note that $ANSWER is a string and must be compared to a string value.
    in this context "yes" is a string but yes is not a string.
You also must make the comparison test in each case, both before and
after the -o above. Your construct would ask " does $ANSWER = yes
evaluate to true?"  OR "is YES true?".  This is two different questions
and does not get what I think you intended as a result.

Les' answer below would also accept a single key response.
