GO
/****** Object: StoredProcedure [dbo].[procDeliveryStock] Script Date: 04/26/2014 04:22:34 ******/
SET ANSI_NULLS ON

ALTER PROCEDURE [dbo].[procDeliveryStock]

@description VARCHAR(50),
@dosage VARCHAR(50),
@selling MONEY,
@receiving MONEY,
@qty INT,
@plus INT,
@minus INT,
@stock INT 
)
AS
BEGIN
SET NOCOUNT ON;
BEGIN TRANSACTION 
INSERT INTO Delivery
(
id, date, description, dosage, qty, selling, receiving
)
values
( 
@id, @date, @description, @dosage, @qty, @selling, @receiving
)
IF @@ERROR = 0
BEGIN 
INSERT INTO StockCard
(
descripton,dosage,[+],[-], stock
)
VALUES
(
@description, @dosage, @plus, @minus, @stock 
)	
IF @@ERROR = 0
BEGIN	
COMMIT TRANSACTION
END
ELSE
BEGIN	
ROLLBACK TRANSACTION	
END
END
ELSE
BEGIN
ROLLBACK TRANSACTION
END

END

My problem is it is not saving in the database but there is no error on runtime.
