First let me explain I'm a truck driver and I work on a 70 hr 8 day cycle. We get back what falls off at midnight each day on the 9th day. I can get it to figure the 8 day cycle no problem. Its when I do a restart and get a "0" in there. I need it to start adding from the "0" for the 8 days. I've tried adding restart in there to have it do it but im not good enough for that kind of formula. Can I do that if so what would the formula be?
