            Dim intReleased As Integer
            Dim lngGate2ID As Long

            DoCmd.Hourglass True

            'Get received pieces.

            intReceived = grecSQL!Received
            grecSQL.Close

            'Get released pieces.

            intReleased = grecSQL!Released
            grecSQL.Close
