Jim, on LHS of your rule, you are actually testing
(test
(and(= ?servicecode 847314565)(= ?quantity 1))
)
AND
(test(or(= ?amount 4.17)))
so make no differenec if you put "or" or "and" inside the second test.
Maybe that is what you need?
(test
(or
(and (= ?servicecode 847314565)(= ?quantity 1))
(= ?amount 4.17)
)
)
