Kevin,
Sorry to steal your instructor time for free, but out of curiosity... Would have it mattered if recursive was turned on? I would think that as the second call to the trigger there would be no records complying with WHERE Inserted.nStndCost # Deleted.nStndCost as the only field updated within the trigger was dStndCost, thus ending the trigger and the recursion with some overhead.
