I have two columns ( A & B).Into the b column i have same value (138159,138159).It appears two times.

I just want to build a formula, where it will get a same value it will count as 1. That means, i am getting two 138159, but formula will treat as 1. and finally it will count the whole b column value.
That means,
0 is here 10 times and other value is also 10 times, but 138519 appears 2 times, so it will counted as 1, so other values are 9 times.

So my expected output will be 10+9=19

I have written following formula for that

=+COUNTIF(K20:K39,0)+9

I did manually. and it’s driving me crazy.

can you guys help me for that.

any suggestion is really appreciable.

=SUMPRODUCT((B1:B20<>0)/COUNTIFS(B1:B20, B1:B20))
