Take a look at the two scrolling lists in the bottom half of the window. In the scrolling list on the left side of the window, each box numbered 10 through 14 on the W-2 form is represented by a field in the list (labeled “W-2 Boxes”). Each of these fields contains a box title and number as it appears on the form. In the scrolling list on the right side of the window, the wages, deductions and taxes that are used to calculate each of the boxes is displayed.
Notice when you click a field in the scrolling list on the left side of the window the title of the scrolling list on the right side of the window changes to reflect the name of the field you clicked on the left. In the next step, you’ll use this functionality to mark the elements that will be used to calculate each W-2 box.
