That may be the only way Base handles Time. If that's the way Base works, then you might try to create a text-field to handle the 1:23.45, and a real number field to handle the equavilent 83.45. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@openoffice.org For additional commands, e-mail: users-h...@openoffice.org
