Wasn't sure the best way to word it. But i am tryign to find a way to create and "average" of our hours over the past 5 or 10 deliveries, but also auto updates. we have a prior hours, driven hours then total hours. Say B11, 12, 13. So B11 would show 1000 hrs, B12 would say 15 hours, B13 would show 1015 hours. Every day we update the hours in B12 for todays value. But is there a way to keep a running previous total? Like the last 5 days say B6 - B10 will keep the most recent enteries while deleteing the previous enteries? We do this on another sheet to get an averge time per truck, but trying to see if i can combine it all on to 1 page.
