Error Checking
Error
Checking works like Spell Checking. Errors can be marked and
corrected one at a time, or Live, as you work on your formulas.
Before
You Begin: Make a Mistake
Select Cell
E8.
Enter this
formula: =C7*D8.
What Do
You See? This formula does NOT match the formula above or below
it. So, Cell E8 has a error mark, a small triangle in the upper left
corner.
Keep
going, please...
