Hi,

I have two tables first one is showing number of involuntary resignations each month during 2017, 2nd table resignations during 2018 for locations A,B,C,D,E, F, 3rd table shows the total headcount by month for 2017, and last table is headcount for 2018. My question is: how to calculate rolling 12 months? what is the best formula to calculate rolling 12 months over month
