Conditionally formatting duplicates

We are now going to apply the same logic used in the previous two exercises.

However, we are now going to do it with conditional formatting.

This will create a more readable report where the duplicates are easy to see.

Specify fixed ranges for the formulas in this exercise.

Identifying a fixed range with $'s (A$3:A$18 in this exercise's case) usually produces the same results as referring to an entire column (A:A), but fixing a range is more precise while using the entire column is more flexible.
