First of all you dont need to add t1,t2. We name the tables as t1,t2....if there are more then 1 table.
try removing t1 and t2 and then fire the query.

SELECT * FROM transactions WHERE TotalAmount < (SELECT SUM(TotalAmount) FROM transactions WHERE TransactID = TransactRefID) ORDER BY ActualDate DESC

Let me know if it works or not
