I have the following info on an Excell 2003 sheet:

column K column M
10/01/2006 10/21/2006
11/03/2006
11/28/2006
12/01/2006 12/22/2006
12/18/2006 4/8/2007

In other words, some cells have both dates, some only one, some neither. I
only want to return the ones where ONE cell in the row is blank or null.
Thanks so much!!!!
