Am I correct in thinking you want to calculate the sum of groups of ABC.C's differentiated by ABC.A?<div><br></div><div>An activation for the third rule is being created each time an ABC is inserted into WM. First with one ABC, then with two and so fourth.</div>
<div><br></div><div>What you want is to ensure that "processing" for rules 1 and 2 complete first and then rule 3 works on the results in WM. This can be achieved with salience on the three rules; lower on rule 3 than 1 and 2 to ensure it's activations execute after rules 1 and 2 are finished operating on all facts.</div>

throwing an error because $lfna_SEI and $r_SE are not bound in the last
rule and assuming chkRuleExpre is constant over time). Rules do not
normally execute in any sequential order (unless you explicitly make them so).
As the facts are inserted into WM they are matched against your rules and
activations scheduled. When all facts are inserted into WM and you call
fireAllRules the activations are played out and "truth maintenance"
ensures the "result" of their firing is consistent with the facts in
WM (either inserted by rules or the programmer). This is in essence "how
inference engines" work.</span></font></p>

session) you insert more ABC's then you'd have to expect the last rule to be
re-evaluated - following another call to fireAllRules. So in part when rule 3
ultimately gives the "correct" answer depends upon when you stop
inserting ABC's.</span></font></p>
