Counting Existing Facts in the RHS of Clips Rules

I think the issue was by ths following , How do you test for fact existence in the RHS of rules in Clips? I'm trying to design a rule that will "score" the current state by counting how many goal facts exist. It's obvious how to test for facts in the LHS, but I can't find how to do the equivalent in the RHS. code :
(deftemplate score
(slot value))
(deftemplate goal1)
(deftemplate goal2)
(deftemplate goal3)
(deffacts start
(score (value undefined))
(goal1)
(goal3))
(deffunction ecount (?g)
(if (anyfactp ((?f ?g)) TRUE)
then (return 1)
else (return 0)))
(defrule scorestate ""
?score < (score (value undefined))
=>
(modify ?score (value (+ (ecount goal1) (ecount goal2) (ecount goal3)))))

I wish this helpful for you In excel you can calculate that without a helper column if you use this formula =SUMPRODUCT((COUNTIFS(A$2:A$11,A$2:A$11,C$2:C$11,"<"&C$2:C$11)=0)*(B$2:B$11=E2))

I hope this helps you . None of the solutions in your link are both particularly good and comprehensive enough to modify, in my opinion, so I will be posting a better one. Also your requirements are also not quite specific enough, so I've made up a few extra ones. code :

it should still fix some issue Trying to figure out how to count the number of leading zeros in an excel cell. The value within the cell can be comprised of both numbers and letters or just numbers or just letters. The column is formatted as a text column. , Try: code :
=SEARCH(LEFT(SUBSTITUTE(TEXT(A1,"@"),"0",""),1),A1)1

I hope this helps . I want to return true, if a fact (A) is declared only once in the Prolog database, return false otherwise. For instance, if we have: , A shorter version of @twinterer answer, using pattern matching:
