Can anybody think of a way to allow _user to decrease a field value, but not increase it? Increments would only be allowed to _admin. I can only think to compare the new value with the old one and see if it is greater or less.
Would that work in a validation function, and is it secure? I'm trying keep as many update actions to the client-side. If I let admin do all the updates then I have to use an Ajax call to the server. Marcus
