I have a spreadsheet that I am building a timing calendar off of, ex. a3 is the startdate, then a4 takes what is in a3 and adds 2 days to that, a5 looks at a4 and adds 1 day to that, etc. What I need is a formula for that will look at both a3, a7 and a15, determine which date is the most recent grab that date and add a certain number of days to it. I am needing the formula to be able to change, if suddenly the dates change in the cells the formula is looking at. Is this possible?
