Nico Hallas runs Hallas Realty, a small but growing real estate agency in Columbia, South Carolina. He keeps track of the listings of his four agents in an Excel workbook and asks for your help in updating and analyzing the data. Switch to the Dahl worksheet, which contains a table named Dahl for Louisa Dahl's listings. Unfreeze the top row of the worksheet because the worksheet is not long enough to scroll.
