Nothing wrong with this rule. Are you using the "watch" function to
monitor what's going on, or just relying on your printouts?

Thanks, I've had a go with that but I still can't get the output
I'm looking
for. The structure of the defrule is
(defrule apples-now
(answer (ident thisweek) (text ?i))
(answer (ident lastweek) (text ?j))
(test (< ?i ?j))
=>
(printout t "You have less apples than last week" crlf))
ident is the question being asked and text the answer. The two
questions are
represented in the deffacts (there is another rule that
automatically asks
lastweek after thisweek, providing the answer to thisweek was > 0).
The
system just doesn't seem to fire this method, and I can't figure
out why.
Not sure if it's something to do with taking variables from two
different
questions or something.
