Chas, and anyone else who sneaks a peak, here's a link to a pretty good article on developing Data Access Pages in Access.

It's a fairly comprehensive document that covers quite a lot.

Also, on an unrelated topic.... here's a good article on how VBA is stored, compiled, and ran...

Thanks Derek,

Will have a look soon. I've just been away (Dallas, Miami and then Bogota so a bit exhausted!!)

Cheers
