Count unique distinct values if condition is true

问题

I try to count the unique values in list but they have to fulfill the condition I have set.

{=SUM(IF($A$1:$A$25=$D$2; 1/COUNTIF($B$1:$B$25; $B$1:$B$25); 0))}

There the first 25 rows of the data as example.

How to count unique distinct values if condition is true in Excel?
