create a forumla based on date
I need to create a formula based on date. I need to creat a calcualte to
include other cells only if they meet certain date requirements. The cells
will meet the requirements a certain period of time then will need to be
removed from the formula. I am trying t automate the worksheet so I don't
have to update it once a month to exclude the previous 4 weeks. How can I do
this?
