title: Excel Countif Date in column A is greater than column B
body: <p>Columns A and B both have dates.  If the date in column A is greater than the date in the same row of column B, the row should be counted.  To add context, I am trying to count the number of rows where the completion date is past the due date.  How can this be accomplished?</p>
  
  <p>Thanks.</p>
