DataSource Controls :: Invalid Object Name 'dbo.pages_Allowed'

I have created my function as follows

USE [fedach]
GO
/****** Object: UserDefinedFunction [dbo].[pages_Allowed] Script Date: 05/18/2010 14:14:34 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[pages_Allowed] (@username varchar(35))
RETURNS varchar(30) AS BEGIN -- Declare the return variable here DECLARE @pages varchar(30)
DECLARE @PRvalidate tinyint,@PRdownload tinyint,@PRupload tinyint, @Pages as varchar(35)
select @PRvalidate=Rvalidate,@PRdownload=Rdownload,@PRupload=Rupload from tblPermittedpages where Username=@username;
select @Pages = case
when @PRvalidate=1 and @PRdownload=1 and @PRupload=1
then 'Admin'
when @PRvalidate=1 and @PRdownload=0 and @PRupload=0
then 'Validate Only'
when @PRvalidate=0 and @PRdownload=1 and @PRupload=0
then 'Download Only'
when @PRvalidate=1 and @PRdownload=0 and @PRupload=0
then 'Validate and Download' End;
return @pages
END

But when i am running the function i am getting the error as Invalid object name 'dbo.pages_Allowed'. can any one tell why?
