Alerting trouble

Maybe I am going about this the wrong way. The FactorySQL group is setup on a trigger to only insert into the database when MillStatus is equal to 1. So if I setup the alert directly on the item it never becomes 0. This causes the alert status to always be 1. So I setup an action item to try and solve the problem. How would you go about being able to tell when the MillStatus tag is 0 and when it is 1?
