Yes, as I said, it would be
(calling goToSlide "TEST" (+ ? slide 1))

Hi,
I used: (calling goToSlide "TEST" + ? slide 1)
but I am getting:
Jess reported an error in routine Value.intValue
while executing (calling goToSlide + ?slide 1)
while executing defrule MAIN::SettingStateAccordingToRoom-rule1.
Message: '+' is a symbol, not an integer.

In Jess, parentheses always have special meaning; most of the time,
they mean "this is a function call". So (?slide) would mean "call
what's in ?slide as a function", which is definitely not what you
want. The "+" function, like all Jess functions, is called using
prefix notation; the quantity "three more than ?slide" is written
(+ ?
slide 3) .

Hello to all community,
I am trying to bind an int variable e.g slide
and then to use it's value plus a different number,
e.g slide + 2, slide +3.
How I Can Do that, the following doesn't work.
(defrule Rule1
...
=>
(bind ?slide 4)
(calling goToSlide "p1" ?slide)
(calling goToSlide "p2" ((?slide)+1))
(calling goToSlide "p3" ((?slide)+6))
...
)
thank you in advance!
