Dynamic target in measures

Hello All,

I need a help with a dynamic target and according to this target I would like to calcualte a measure. Let me give you some example.

I have a list of countries and each of them have their own target, for example Germany - 3 days , Spain - 4 days to process the ticket.

The measure needs to count how many tickets were closed within this target.  So I tried something like this for Germany : Tickets within KPI = Calculate(Count(Table1[Column1]),(Table1[Days]) <= 3) and it works fine but unfortunately I have a lot of the countries and I would like to avoid creation that many measurments with different target.

Is there is any way to create a dymanic target so when I pick  up in the slicer Germany the Tickets within KPI measure will automatically count a rows with days below or equal 3 and when I choose Spain it will count rows with the 4 days below or equal  ? I tried to created a table and used SWITCH function :

Dynamic Target = SWITCH(Targets[Country]),

2 "Germany", 3,

3 "Spain", 4)

but when try to use it in the measure : Tickets within KPI = Calculate(Count(Table1[Column1]),(Table1[Days]) <= [Dynamic Target] ) I have a warning message  " A function 'CALCULATE' has been used in a True/False expression that is used as a table filter expression. This is not allowed."

I am not Power BI expert so may thinking may look stupid for you but I will aprreciate any help. Thanks !
