Hi,
The rule
(defrule s_24_sendlinks-texts
(send-links ?y)
(web-page (URL ?y) (links-texts $?t) (links $?l))
(knowledge-to-send (name-other-agent ?a)
(terms-links-texts $?w))
(test (> (length$ (bind $?x (search-in-list $?w $?t $?l))) 0))
=>
(insert-link ?a $?x))
(insert-link is a function) has this parsing error:
ess reported an error in routine ReteCompiler.eval.
Message: Unbound variable found in funcall: x parsing defrule
s_24_sendlinks-texts .
Program text: ( defrule s_24_sendlinks-texts ( send-links ?y ) ( web-page

bind $?x ( search-in-list $?w $?t $?l ) ) ) 0 ) ) = > ( insert-link ?a
$?x ) ) at line 25.

How do I bind a Value in the LHS to use it in the RHS? I also tried ?x
instead of $?x.
Thx in advance
