Using distinct in expression?

[lucasx15]

Hello everyone, I needed to create an expression using if and maketime, but I am not able to apply DISTINCT in count. How would you proceed in that case?

=count(
		if((DT_LOS_PROC -DT_PRESC)<=MakeTime(0,30),  %PRIMAY_CLIENTS)
		
		)

Hi, have you tried?

=count(Distinct
  if((DT_LOS_PROC -DT_PRESC)<=MakeTime(0,30), %PRIMAY_CLIENTS)
)
