Append records using two variables

I have a table: tblSchedule in SQL Server with fields:

Schedule_ID (int PRIMARYKEY Autoincrementing), Schedule_CostType (char 16), Schedule_Section (char 16) , Schedule_No (char 16), Schedule_Order (float 8), Schedule_Desc (char 32), Schedule_Unit (char 16), Schedule_Qty (real 4) ,tender_ID (int FK)

I want to select all records where Tender_ID = a variable  tender_ID_Original
and append them in the same table but with Tender_ID = a variable  tender_ID_New
(Note: there are no integrity problems as The FK tender_ID_New already exists)

I have written the sp :

ALTER PROCEDURE procNewSchedule
(@tender_ID_Original int,
@tender_ID_New int)
AS
SET NOCOUNT ON

INSERT INTO
dbo.tblSchedule(Schedule_CostType, Schedule_Section, Schedule_No, Schedule_Order, Schedule_Desc, Schedule_Unit, Schedule_Qty,tender_ID)

SELECT     Schedule_CostType,Schedule_No,  Schedule_Section, Schedule_Order, Schedule_Desc, Schedule_Unit, Schedule_Qty,@tender_ID_New
FROM         dbo.tblSchedule
WHERE       Tender_ID = @tender_ID_Original
              
SET NOCOUNT OFF

When I run it asks for the variables OK and seems to run OK but I get the message 'The stored procedure executed successfully but did not return records"
What have i done wrong?


also I want to run thus sp in Access using VBA code but I'm not sure how to pass the variables

Private Sub btnAppendSchedule_Click()
Dim tender_ID_Original, tender_ID_New  As Integer
Dim vSQL As String

tender_ID_Original = Forms!frmRepeatSchedule.cboTenderOld.Column(0)
tender_ID_New = Forms!frmRepeatSchedule.txtTenderNew

vSQL = " procNewSchedule ??????? "

DoCmd.RunSQL vSQL

End Sub

Thanks in advance
