I have the need to always reference the last 6 sheet tabs for averages. I am looking for a way that the new tab will look at tabs 2 through 7 without having to retype the reference. Example would be first sheets 1-6 then 2-7 then 3-8 and so forth after adding new sheets 7 and 8. Attached is a file as an example. Any help or suggestions would be appreciated. Thanks
