使用多个标准计算行数

Question

I am going to count rows based on the values of two columns (ie, count if the Priority is "1" and Status is "not defined"). Here is an example:

Priority	Status
1	implemented
0	implemented
1	not defined
0	not defined
0	implemented
1	not defined
1	implemented
1	implemented

which I would like to get 2 because there are only two rows with Priority = 1 and Status = "not defined".

I tried the following but not successful in this regard:

=SUMPRODUCT((COUNTA(M3:M20))*(J3:J20="not defined"))

Answer 1

Use either of the one, refer image

=SUMPRODUCT(($A$2:$A$9=1)*($B$2:$B$9="not defined"))

=COUNTIFS($A$2:$A$9,1,$B$2:$B$9,"not defined")
