I have a basic schema using numbers; {lower, upper, qty}. I set the max and the min parameter for each and then used a formula to create the number for upper as lower * 3. It seems thought that a formula reference will exceed the max parameter. So if lower is 20 it will set upper to 60 even if the max for upper is set to 50.
