Can someone help me write a simple formula for the following problem? I have a 3 column table. First column is the date, second column is the # of cases. 3rd column is the increase % of cases. I simply want to take today’s case value and find the increase from yesterday’s. How do I reference yesterday’s cases? How can I write a formula like this? ((todayCases - yesterdayCases) / yesterdayCases) * 100
