"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Thank you for your help, I did not realize that I did not sent you the beginning of the code, please find it attached.
Fabrice LambertConsultingCommented:
It looks like an ambiguity issue between DAO recordset and ADO recordset.
(guess you referenced the ADODB library ?)

Always fully qualify your variables:
DAO.Database instead of Database.
DAO.Recordset instead of Recordset.

Also, think about using to late binding instead of early binding (that is: using explicit references).
