I am trying to get a weekly average from a temperature column. The excel
spreadsheet has a months worth of dates and an average for each day. I found
the weekday formula and can convert weekdays to a number from 1 thru 7. From
that I want to use the IF logic formula that day 7 it would average backwards
7 days (cells). There might be an easier way to do it but getting the syntax
right is also a problem. Any help would be appreciated.
