Adding transaction to stored procedures

Question

I really need your help with transaction in the following stored procedure.

ALTER PROCEDURE [dbo].[UP_SAVE_EMPLOYEE_DETAILS]
                                            @StoreID int,
                                            @StoreBranchID int,
                                            @DepartmentID int,
                                            @FirstName nvarchar(30),
                                            @LastName nvarchar(20),
                                            @PhoneNumber nchar(15),
                                            @Email nvarchar(50),
                                            @Street nvarchar(50),
                                            @City nvarchar(25),
                                            @State nchar(15),
                                            @Country nvarchar(15),
                                            @IsEmployee bit,
                                            @IsCustomer bit,

                                            AS
SET XACT_ABORT ON

DECLARE @PDID INT
DECLARE @ADDID INT

--BEGIN TRANSACTION
                    EXEC @PDID = UP_INSERT_PERSONAL_DATA
                                                                @FirstName,
                                                                @LastName,

                                                                @Email


                    EXEC UP_INSERT_PERSONAL_DATA_RELATIONSHIP

                                                                 @StoreID,
                                                                 @StoreBranchID,
                                                                 @DepartmentID,

                                                                 @IsCustomer,
                                                                 @IsSupplier,
                                                                 @IsReseller


                    EXEC @ADDID = UP_INSERT_ADDRESS @PDID,
                                                    0,
                                                    Street,
                                                    @City,
                                                    @State,
                                                    @Country,
                                                    @PhoneNumber,
                                                    '000-000-0000'

                    IF (@PDID > 1 AND @ADDID > 1)
                        RETURN 1
                    ELSE
                        RETURN 0
--COMMIT TRANSACTION

when I try the transaction I have the following error.

 

Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 0, current count = 1.

 

Thank you!
