Read the measure before the formula
A cell address locates information, but the label tells you what that information means. B2 might contain visits, dollars, or minutes; the number alone does not say. Check the column heading, units, period, and whether rows represent distinct observations. In this lesson, the supplied spreadsheet counts visits over four specified days. It does not automatically count unique visitors or describe a full year. Use the printed cell map so the task is possible without opening a spreadsheet service.
