I don't understand why they marked my answers wrong? I have copied the transactions directly from the list they provided. Which is for Lisa and Teresa's return allowances. The first time I put dates 11/7 and 11/25... then I tried to input the original dates that they made the purchase (which is the current answer listed below and still marked incorrect). What am I doing wrong?
