Your rule matches individual facts that look like "(a 1)", not slots
inside of a "t" fact, which is what you're actually asserting. You
have to match the "t" fact explicitly, and furthermore, you have to
match it all as part of one pattern. The equivalent, correct rule
could look like
(defrule r1
(t (a ?a) (d ?d) {b > ?a} { c > ?d || b > ?d })
=>
(printout t "test" crlf))

Hello,
I try to write a rule to compare values in two slot but it does not
fire. See the jess code below. Can anyone point me the issue or a
better way to do it?
