What's wrong with my query?

I keep getting error "Too few parameters. Exptected 1" when I run this:
"UPDATE Users SET TrialExpired = True WHERE Trial = True And DateRegistered < #" & (Date - 5) & "#"

What's wrong with my query?

Thanks

One of your fields are blank or invalid. Look at your WHERE clause. Look at the DateRegistered in your query.

Nevermind, I had forgotten to add one of the feilds to the DB.
