I am building a function that tests the dates listed in four (4) columns. When testing each date in each column, one of my tests measures if the date occurs previous to the date that is being used as a reference. Since the reference material says that COUNTIFS handles blank cells as -zero- values, my assumption would be that if I made a statement like:
.. that the count would equal all rows that are sooner (smaller) than "9/17/11" all the way down to zero -- which should include blank rows where dates have not been entered yet.
This is not the case, however, as the number being returned is just the number of rows that actually have a date -- and not any of the blank rows.
Before anyone suggests using a different function, I'm pretty much stuck with using COUNTIFS unless I write a novel about what I'm trying to do and how I'm trying to make it work (which isn't probably worth all the effort). My idea is working 98% so far, except for this one little part...
