Stored procedure incorrect?

[stockton]

I have written the following Stored Procedure and need input as to what could be wrong with my coding or is there a possibility that not getting the correct results is not in the procedure at all?

ALTER PROCEDURE spIssueScannedTickets
        @iEventID int,
        @MemberNum nvarchar(12),
        @BatchSize int,
        @FirstNumber nvarchar(12),
        @LastNumber nvarchar(12),
        @SlotsBalance int,
        @TableBalance int,
        @BonusBalance int,
        @UserID int
AS
DECLARE @Result int
SET @Result = 0
BEGIN TRANSACTION
if  (@SlotsBalance>0)
INSERT INTO TicketsIssued (Date, EventID, MemberNumber, EarnType, NumTicketsIssued, Turnover, UserID)
         VALUES (GETDATE(),@iEventID,@MemberNum, 'Slots', @SlotsBalance, 0, @UserID)
SELECT @Result = @@error IF @Result <> 0 BEGIN ROLLBACK TRANSACTION RETURN @Result END

if  (@TableBalance>0)
INSERT INTO TicketsIssued (Date, EventID, MemberNumber, EarnType, NumTicketsIssued, Turnover, UserID)
         VALUES (GETDATE(),@iEventID,@MemberNum, 'Tables', @TableBalance, 0, @UserID)
SELECT @Result = @@error IF @Result <> 0 BEGIN ROLLBACK TRANSACTION RETURN @Result END

if  (@BonusBalance>0)
INSERT INTO TicketsIssued (Date, EventID, MemberNumber, EarnType, NumTicketsIssued, Turnover, UserID)
         VALUES (GETDATE(),@iEventID,@MemberNum, 'Bonus', @BonusBalance, 0, @UserID)
SELECT @Result = @@error IF @Result <> 0 BEGIN ROLLBACK TRANSACTION RETURN @Result END

INSERT INTO BundlesIssued (MemberNumber, EventID, BundleSize, FirstNumber, LastNumber, DateIssued, UserID, Invalid)
        VALUES (@MemberNum, @iEventID, @BatchSize, @FirstNumber, @LastNumber, GETDATE(), @UserID , 0x00)
SELECT @Result = @@error IF @Result <> 0 BEGIN ROLLBACK TRANSACTION RETURN @Result END

COMMIT TRANSACTION
SELECT @Result = @@error IF @Result <> 0 RETURN @Result
SET @Result = @BatchSize RETURN @Result
GO

As far as I am aware what I have written should give an "all or nothing situation". In other words either all tables are updated or none are.
Comments please.

Looks like it's rolling back.

Try executing it as a series of t-sql first. Define the parameters as variables and hard code the values.

Try putting a PRINT 1 or SELECT 1 (then SELECT 2..then 3...then 4) on all rollback. You'll see where it's falling. Like DEBUG mode
