I have a spreadsheet that I update weekly with several formula's in it and
contains several weeks of information. Each week when I go in and update it
he final step is to change the number of weeks I am dividing by. Example this
week was 28, next Friday I will need to divid by 29. This has to be changed
in 3 locations on the SS. Is there a way I can add a fromula that I can
change that will change this number in all 3 locaitons and only have to
change it once.
