please take a look to see if you find any issues.
I know the solutions do it this way.  When I was going through the course I don't remember if it was me or another student, but Kevin was asked about this.  He said that a success message was a good idea because the less information you give out about your database, the better.  Feel free to ask him on the discussion board for confirmation.  Just because you are doing it this way in another app as well doesn't make it the right way :frowning: .  I wasn't trying to say you were wrong in doing it this way, I was just trying to make you think about possibilities.  The reason for this is the same reason you want to use tokens so users do not know how many items are in your db.  Anyway, good job.
