Transaction Error

Folks,

I'm completly confused. I'm trying to execute the following stored procedure:

BEGIN TRY
BEGIN TRANSACTION

DELETE FROM Account_TB (i've purposely mistyped the table name to throw an error)
WHERE PK_AccountNumber_STR_ID = @userID;

COMMIT
END TRY
BEGIN CATCH
IF @@TRANCOUNT > 0
ROLLBACK


-- Raise an error with the details of the exception
DECLARE @ErrMsg nvarchar(4000), @ErrSeverity int
SELECT @ErrMsg = ERROR_MESSAGE(),
@ErrSeverity = ERROR_SEVERITY()

RAISERROR(@ErrMsg, @ErrSeverity, 1)
END CATCH


When i execute the stored procedure, i get the following error:

Msg 208, Level 16, State 1, Procedure up_DeleteAccountInfo_Web, Line 17Invalid object name 'Account_TB'.Msg 266, Level 16, State 2, Procedure up_DeleteAccountInfo_Web, Line 17Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 2, current count = 3.

The activity monitor shows that the transaction is still running even after the stored procedure finished executing. Any ideas? Please help me with your advice.

thanks,
jon
