I need to count how many cells in a specific column are below a certain date. Also, at the same time, the counter should only be increased, if some other cells next to each cell being counted are empty.
Example
Columns:
Date1 Date2 Date3
01/02/2012 01/02/2012 01/02/2012
01/02/2012 01/02/2012 01/02/2012
01/02/2012 01/02/2012 01/02/2012
01/02/2012
01/02/2012
01/02/2012 01/02/2012 01/02/2012
I need to count how many cells in the column Date2 are below some date AND where date1 + date3 are empty. The result would be: 2
Currently, i only know how to count the number of cells below a certain date:
=COUNTIF(ArrayFormula(Mona!$F$4:$F$400); "<="&$AY12)
But this doesnt work with the other criteria :(
I am using google-docs
REAL DATA
Columns:
B C D E
I need to count the number of cells where C is below AY12, and where B, D and E are empty ("")
