Delete Statement

I would like to delete entries that are older than seven days. the db is Access and here's the sql:

strQ = "DELETE Registration.RegDate, Registration.FirstName, Registration.LastName, Registration.Street, Registration.City, Registration.State, Registration.Zipcode, Registration.Email, Registration.EmailConfirm, Registration.InStore, Registration.WebSite, Registration.RegTime FROM Registration WHERE (((Registration.RegDate)<=DateAdd('d',-7,Date())))"

I was running this query from the start page.It didn't work there.I tried to run it on the page that returns the Select statement and it failed there too.
