Hi,

quick newbie question about the when clause in a rule. eg can i get the fact to be tested from the result of two other inputted facts?

details.HOME_MATCH_SCORE - details.HOME_FULL_TIME_SCORE > details.AWAY_MATCH_SCORE - details.AWAY_FULL_TIME_SCORE

I assumed this would work fine but it doesn't recognise the '-' as a minus!

Thanks in advance

Alex
