Question

I want to count all the blank fields in column B where column A contains values. I cannot find an appropriate method of doing this in Excel 2010.

I am also counting other values in column B, for example =COUNTIF(B:B,"AST005").

Now I need to count the values in column B where column A has a value. If I use =COUNTBLANK(B:B) it returns 67500 where in reality it should return 15. How do I alter my formula?

Answer 1

If I read your quextion right, you want to count rows where Column A is not blank AND Column B is blank?

For example

    A    B  
1   a    q
2   s
3   d    e
4        r

would return 1

=SUMPRODUCT((A:A<>"")*(B:B=""))
