I have to columns that are of type date. There is a third column that
I want to indicate, for each row, if the 1st column's date is more
recent (i.e. greater) than the second column's date. If that is true,
I want the text "Yes" to be entered in the third column for the row in
question. If it isn't true, I want there to be no text in the third
column for the row in question.

I've seen tons of date comparison posts here, but they are always using
actual cell identifiers (i.e. A20). I need a more generic function
that will work on the column. The requirement is when someone updates
any date in this spreadsheet that the third column cell will update
automatically. Is this possible in Excel?

Thanks!
