If I could put my 2 cents in...

If your using the above code and not getting anything in return, my
guess is that your error is somewhere else in your database. These can
be hard to find, as I have had to track these down.

Make sure you use Error Handling everywhere, but even then that
doesn't help sometimes.

My next guess would be to try steping through your code one by one on
a fully licenced Access machine using someone else's login.
