Well, I've had a bit of a play and I can't see how to do it. I don't really understand the relationships between Access, DAO and Jet, but as far as I can tell you can only run macros within an Access application and if you open your database with DAO under Excel it doesn't seem possible. Perhaps one of the experts out there can explain or help. If nobody else posts here it might be worth starting another thread - and I'll keep out of it!!
Sorry not to be more help,
Tony
