I have 2 column A & B. Both columns have 100s of rows but they may not all
be filled, many will be blank. I want to know the number of days there are
(total) betwen the two columns when there is an entry in both columns plus
the numbers of days there are from today (total) when only column A has a
date. If column B has a date column A will also have a date.

Example

A B
1/2/09 2/3/09
3/6/08

6/7/09 7/4/09

4/5/08

3/6/09 3/30/09
