( defrule resultthisorthat ?result <- ( result ~ ?m & : ( < ?m 200 ) & ~ ?m & : ( > ?m 200 ) ) = > ( retract ?result ) ( printout t "Please enter a number between 0 and 2000" ) ( assert ( result ( read ) ) ) ) Jess replies witha an error that you cannot begin with a negation. I tried putting the whol thing into brackets but Jess replied it was an invalid slot. Help.......:-).
