The mathematical expression patch is pretty fussy about nesting, I've found before that it doesn't evaluate these things the way I expect it to. Anyway, it's fixed by forcing correct evaluation with extra brakets: ((IntegratorResult < Min) && (Value < 0)) ? 0 : (((IntegratorResult > Max) && (Value > 0)) ? 0 : Value)
