I am trying calculate a rolling three month average as each months numbers
are added. For example: If I have values for all the months up to July, I
want to average May, June and July. When August is added I want it to
average June, July and August. I have been doing this by changing the range
in the formula each month, but would like to make it more efficient and user
friendly.
Thanks!
