System.Web.UI.Page.Reuqest' denotes a 'property' where a 'method; was expected

Did you cut-n-past this code or re-type it? I as because your text, cmdSelect = new SqlCommand( "Select book_id, title, passage, date, location where book_id ' " + Request.("ID") +" ' Order by passage", cn ); , does not have an "=" between book_id and the 'value'. Don't know if that would cause the error you are getting, but the database should not like this very much.
