Hi all, I've created an UDF but when trying to access it I'm getting the error message

Server: Msg 208, Level 16, State 1, Line 1
object name 'dbo.fn_dias' is invalid.

to call the udf I'm using:

select dbo.fn_dias('2','210001')

and here's the code:

CREATE FUNCTION dbo.Fn_Dias (@pCuenta varchar(5),@pTipoMovi varchar(6))  
RETURNS table 
 AS  
return SELECT DATEDIFF(Day, (SELECT Fecha
                          FROM   Transac01
                          WHERE  Documento = Transac02.documento1 AND 
				             Tipomovi = Transac02.Tipomovi1), fecha)  as dias
FROM      TRANSAC02
WHERE     (cuenta = @pCuenta) AND (tipomovi = @pTipoMovi) 

At this time I just don't know what I'm doing wrong, so I'd appreciate any help!
