I don't see PagePosition anywhere in your code--are you sure you're showing us the correct error message and/or code?

Anyway, since it's complaining about something not being present, the first thing I'd do is verify that you're in the correct database. (I know you can have a default database for a login, so this may not be relevant, but that's the first thing that comes to mind.)
