I've had six occurrences in the last 36 hours of records being deleted from my critical Work Instruction file.  I have the following programming in my On Form Entry section to try and eliminate record deletion.  This programming has been there for quite some time:

// DISALLOW DELETING EXCEPT BY ADMINISTRATORS

     If @Group = "MASTER"
         {
             NotifyForm(-4) // Allow Delete
         }
     Else
         {
             NotifyForm(4) // DisAllow Delete
         }


Is there some other method or programming to ensure files are not deleted except by one or two individuals?  In my application the MASTER group is limited to myself and the backup person.

HELP!!
