Return value of a stored proc

i have this stored proc


CREATE Procedure dbo.spGetReport(@CourtierID int, @TypeFile varchar(100)) As

Declare @ID int

Select inforapportid, date_debut_periode, date_fin_periode, date_fichier_genere, no_courtier, nom_courtier, no_agent_general, nom_agent_general, no_courtier_autre, nom_courtier_autre, TypeFichier
From InfoRapportRAPFND
Where [no_courtier] = @CourtierID and [typefichier] = @TypeFile

select @ID = inforapportid
From InfoRapportRAPFND
Where [no_courtier] = @CourtierID and [typefichier] = @TypeFile

Return @ID
GO
and there is my code that call this stored proc

With mlpCmd
.ActiveConnection = mlpCNClient
.CommandText = "spGetReport"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("RETURN_VALUE", adInteger, adParamReturnValue)
.Parameters.Append .CreateParameter("CourtierID", adInteger, adParamInput)
.Parameters.Append .CreateParameter("TypeFichier", adBSTR, adParamInput)
End With
this append the parameters to the command

With mlpCmd
'Set parameters values

With .Parameters
.Item("CourtierID").Value = CourtierID
'.Item("TypeFichier").Value = TypeFile
End With
'Execute and Retrieve RS
Set lpRSInfoRapport = .Execute()
lngReportID = .Parameters.Item("RETURN_VALUE").Value
End With

so the stored proc doesnt return me anything but if i build a select whit the same syntax it returns me something, and if i remove the parameter TypeFichier it returns me something too..

can someone helps me to find the problem?

thanks a lot
