Can someone check that for me?

Using the following headings, indicate the effect of each error and the amount of the effect (that is the difference between the entry that was or was not made and the entry that should have been made). Use O if the effect overstates the item, U if the effect understates the item. (Reminder: Assets = Liabilities + Stockholders Equity, Revenues Expenses = Net income: and Net Income accounts are closed to Retained Earnings, a part of Stockholders Equity.)
