Set analysis - multiple variables in comparisson

[#1]

Dear members,

I am using set analysis to count students in their departments.

COUNT( { < [Department]  = {'Math', 'Biology'}  > } StudentId)

Now I need to use parameters Department01, Department02 instead of hardcoded strings.

In Qlik Sence it works only for one parameter:

COUNT( { < [Department]  = $(Department01)  > } StudentId)

I am not able to use two or three parameters. The code below does not work in QS:

COUNT( { < [Department]  = {$(Department01),$(Department02)}  > } StudentId)

I just know it is possible in Qlik View.

Any idea please how to write a code with two or more parameters?

Thanks.
