SumProduct to count Rows with at least one cell blank

[drom]

Hi and Thanks in advance!!
My real table contains many columns but I only need to count the rows where A;B contains at least on cell blank
This table contains a conditional formatting to plot as yellow ifA or B is blank
I do not want to add a new column to this table to get the job done

How about

=SUMPRODUCT(SIGN((A6:A14="")+(B6:B14="")))
