Brian,

The code you sent me is from mmBusinessObject. This code doesn't call your CheckRulesHook() method directly. Check the code, you won't see a call to CheckRulesHook(). Rather, this method calls your business rule object's CheckRules() method which in turn calls your custom business rule object's CheckRulesHook().

What version of MM .NET are you using?
