The formula must be entered exactly as it appears here.
This is telling the Checking Machine the following:
a. If the word in cell B9 (follow in this case) is the same as the word in cell D9
(follow, in this case)
b. Then the words “Great Job” should appear in Cell F9.
c. If this is not true, then the words “Try Again” will appear.
Enter the correct formula for each of the three words you have entered into your table.
