I am trying to customise an events management system that I have built using the 'wizard' that is part of MS Access 2000. However, when I attempt to 'enter attendees', a box saying 'Registration.SalesTaxRate' keeps popping up. I thought this must be coming from a parameter query, but I can't seem to find where it originates. I really need to get rid of it for the system to be usable, as in the UK we don't add sales tax in the same way.

Please forgive my massive ignorance, but I am a librarian with systems interests, not a 'proper' IT person, let alone an Access developer....
