Hi Everyone, Sorry for such a basic question... Have a simple attendance worksheet where entries can be P, Ab, s, or blank. Want to add a formula so that if person has 5 consecutive absences - identified by value of Ab in the cell - change the Ab value in just those 5 cells SW. It is possible that there would be a blank cell in the middle, which should be ignored. I've looked for array formulas but nothing looked promising. Not new to Excel but as you see, use the basics. Thanks so much!! Terry (ps Would be glad to take a class but not sure which class would over this...?)
