Now I am working on my 90 day formula, however, I have gotten a basic principal in columns XYZ on the year to date tab. I still need for it look back anytime someone has received no points in 90 days. If employee has missed no time for points after 90 days 1 point falls off. Is there a formula that I could add to capture this with a new column? This went into effect 9/1/2014.
