[rules-users] Formula error in Business Rule(Guided editor)

Hi, Currently I am facing following issue while inserting a formula in Business Rule(Guided Editor): 1) I have written following formula to be executed in Business Rule(Guided Editor): WHEN 1. The following exists: There is a RuleObject [$r] with: installations < 100 THEN 1. Insert RuleObject: calulatedValue = $r.installations*3 But it gives error 'Unable to analyse expression' when i try to Verify the rule. I want my end result will be a calculated value instead of Literal value. Please let me know the correct syntax to use formula in this type of rule. Thnaks. -- View this message in context: http://drools.46999.n3.nabble.com/Formula-error-in-Business-Rule-Guided-e... Sent from the Drools: User forum mailing list archive at Nabble.com.
