(not ... is true when no facts match. "x" would be undefined in this case.
You could probably do this instead...
(LOAN_AMOUNT ?x&:(>= ?x 5000)
Unless, what you are trying to do is display a message when there are no
LOAN_AMOUNT facts < 5000. Then you can not reference a LOAN_AMOUNT fact in
the conclusion because there won't be any to reference.
