Exercise 2: Inserting an Expression Into a Label Style

In this exercise, you will insert an expression into an existing label style.

After you set up expressions, they are available in the Properties list in the Text Component Editor so that you can add them to label styles. In effect, expressions become new properties that you can use to compose a label style.

Expressions are unique to a particular label style type. Only those properties that are relevant to the label style type are available in the Expressions dialog box.

This exercise continues from Exercise 1: Creating an Expression.
