I have a rotation list that I would like to have automated. I work a 7 day
rotation.
a1, a4, a7, needs to rotate. a2,a3,a5,a6,a8,a9,a10 move down one spot

a1- Jill amy Andy
a2 Mary Bj Adam
a3 Jean Mary Bj
a4- Andy Jill Amy
a5 Lee Jean Mary
a6 Jim Lee Jean
a7- Amy Andy Jill
a8 Lori Jim Lee
a9 Adam Lori Jim
a10 BJ Adam Lori

I am just learning functions. Is it possiable to make this automated??
All replies are appreciated. Thanks.
