Hi,
I have 2 columns with dates. Some of the cells may be empty in any of these columns.
I need to count the number of dates in "col2" that have no date in the same row in "Col1":
In this example, I should get 2 as a result.
col1; col2
01-5-2011; 29-04-2011
"empty" ; 28-04-2011
"empty" ; "empty"
"empty" ; 01-05-2011
Regards,
Élio Fernandes
