Arguments are of the wrong type.

Jeg får følgende fejlmeddelelse:

Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another.
/ucsigncom/purchaseucsign.asp, line 104

Linje 104-5 ser sådan her ud:

objRS.Open "dbo.up_parmsel_ucsigncom ('" & strEMail & "', '" & strDomain & _
                        "')", objConn, adOpenForwardOnly, adLockReadOnly, adCmdStoredProc

Min gemte procedure ser sådan her ud:

SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO

ALTER  PROCEDURE dbo.up_parmsel_ucsigncom
@Email VarChar (50),
@Domain VarChar (80) AS
SELECT Primary_Key_BI, Company_Name_VC, Domain_Name_VC,
Firstname_VC, Lastname_VC, EmailAddress_VC, CCNumber_NV,
CCExpMonth_IN, CCExpYear_IN, CC_Type_VC
FROM Buyer_T
WHERE Domain_Name_VC = @Domain AND EmailAddress_VC = @Email

GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO

Hvad er der galt?
