I'm trying to use a autocalcuating field to take the largest value from a series of modifiers. The example would be you have a +2 from one source and a +3 from another, but they don't stack, only the highest takes effect. If I was working in excel I'd use max (item1, item2, item3). That is not an option that I have found, but the roll engine has the keep highest calls, so I think there is someway to do what I want, but not sure how to do it. Any suggestions? Matt
