This has been killing me for a while now. I just need to count a cell if the date in that cell is greater than or equal to a date in another cell (minus x days).
For example:
A1 2/20/2014
B1 1/20/2014
=COUNTIF(B1, ">=A1-30")
-30 would be minus 30 days. This obviously does not work. Help is greatly appreciated. Thanks!
You were almost there:
=COUNTIF(B1, ">=" & A1-30)
