[rules-users] Struggling with Rule syntax - please help...

I'm having trouble figuring out syntax for my rules - could someone please steer me in the right direction - it's been a frustrating few days and no luck. I need to check existence of various attributes from the SHIPMENT_MOVE fact against a list of values (same list) I fetch from the DB... Get $valuesList from a DAO - then... If SHIPMENT_MOVE.customer_code = "abc" and SHIPMENT_MOVE.reference_code exists in $valuesList OR SHIPMENT_MOVE.customer_code = "abc" and SHIPMENT_MOVE.shipping_code exists in $valuesList OR SHIPMENT_MOVE.customer_code = "abc" and SHIPMENT_MOVE.partner_code exists in $valuesList I have the following rule working fine: $shipment SHIPMENT_MOVE(customer_code = "abc") LookupTableResult ( resultValue == 1 ) from lookupDAO.getLookup(...) But I'm having real problems with writing a rule like this: when SHIPMENT_MOVE(customer_code == "abc", $list contains ship_code) OR SHIPMENT_MOVE(customer_code == "abc", $list contains deliver_code) OR SHIPMENT_MOVE(customer_code == "abc", $list contains port_code) Your guidance will be appreciated - Thanks, James P.S.
