Problem when using if statement and count in same expression

[#1]

Good Morning,

I need to use if statement and count in same expression.  When using the following expression i'm getting no data.

=If(Identity = 'A', count(distinct{<Identity = {'A'}>}[ID]), If (Identity = 'B',count(distinct{<Identity = {'B'}>}[ID])))

[#2]

the syntax is := count (if(condition,value))

[#3]

Try putting the distinct after the set expression:

=If(Identity = 'A' , count({<Identity = {'A'}>}distinct [ID]),

If (Identity = 'B' , count({<Identity = {'B'}>}distinct [ID])))

Or you can create 2 expressions

A:

count({<Identity = {'A'}>}distinct [ID])

B:

count({<Identity = {'B'}>}distinct [ID])
