Countif index match to find how many unique values are equal to zero

Question

I have a excel sheets that looks like something like this

ID |Generation |STNAME

BW1 | 0 | Main1

BW2 | 2 | Main1

BW3 | 0 | Main1

BW4 | 1 | Main1

GH1 | 0 | JHkl

GH2 | 0 | JHkl

GH3 | 4 | JHkl

GH4 | 0 | JHkl

I need to find how many times the column STNAME his less than zero

Main1 | 2

JHK1 | 2

I have been trying to use the index match approach by creating another column and using countifs functions but it doesnt seem to find the correct number of values. I am trying to use the same approach as the link

Answer 1

You should simply use the COUNTIFS function.

Assuming the data structure above where C2:C9 is the values of the column "STNAME":

If you want to know how many are equal to 0, use:

=COUNTIFS(C2:C9,"Main1",B2:B9,0)

If you want to know how many are greater or equal to 0, use:

=COUNTIFS(C2:C9,"Main1",B2:B9,">=0")
