Procedure ’sp_InsertProfile’ expects para

hi guys,

 When i try to insert a record from asp by calling a stored procedure in sql server2000 i am getting the following error.

the error is ...

Microsoft OLE DB Provider for SQL Server error '80040e10'

Procedure 'sp_InsertProfile' expects parameter '@Expect', which was not supplied.

my stored procedure is ...

CREATE PROCEDURE sp_InsertProfile
(
 @Name varchar(50),
 @Expect varchar(500)
)
 AS

IF EXISTS(SELECT Serial_No from Profile_Details Where Profile_ID =@Profile_ID)
 return(0)
ELSE
 INSERT INTO Profile_Details
 (Name,Expectation)

 VALUES

 (@name,@Expect)

RETURN @@IDENTITY

SET NOCOUNT OFF
GO

my asp coding is ...
...
commInsert.Parameters.Append commInsert.CreateParameter("@Expect",adVarChar,1,500,vExpectation)    
commInsert.Execute()

thanks in advance
