GetSelectedCount Not Working as intended

[ss09]

I have a filter which has the following logic: =Pick(Match($(vLanguage),1,2),province,province_french) and it works and gives me a Multi-select filter.

Now the objective is to allow the user to only select one field where the viz is displayed.

My Solution: =GetSelectedCount(Pick(Match($(vLanguage),1,2),province,province_french))=1 However, it always gives me 0, even when I select one province.

Hi

create a variable

vSelectedProvince:
=Pick(GetSelectedCount(province), province, province_french)

in filter use below exp

=Pick(Match($(vLanguage), 1, 2), province, province_french)

use GetSelectedCount on the variable

=GetSelectedCount(vSelectedProvince) = 1

What is to be added here - is what I am failing. I added "=GetSelectedCount(vSelectedProvince) = 1" and it says calculation condition is not fulfilled.
