Display values in KPI only if there's a filter selection

[lailarhc]

Hello.
I have a couple of KPIs and I want them to not show anything unless a particular dimension is selected.

Here's a image of my dashboard:

I want the KPIs in red to only display values if there's an employee or more selected. How do I do this?
I tried putting GetFieldSelection(Employee) and GetFieldSelection(Employee) = Employee on the Calculation Condition in the Data Handling section, but it doesn't work.

How can I achieve this?
Thank you in advance.

Try using this in the KPI measure expression:

=if(GetFieldSelections([Employee])>0,count(Course),'')

It worked. Thank you 🙂
