Sorry, you are screwed <smile> if you are talking about incremental
AutoNumber (but if you were using Random AutoNumber, you wouldn't have
asked this question).
OTOH, you are using AutoNumber incorrectly. The *only* purpose of
AutoNumber is to provide (almost-guaranteed) uniqueness to each Record and
the actual value assigned to each Record shouldn't matter. My users don't
even ever see the values of the AutoNumber Field.
