Dynamic total count of value based on values currently being presented

[gggar]

Hello, 

Currently I have a table

Have a DAX "Total Value Count"

Total Value Count = 
CALCULATE(COUNT([Value])
, ALL(Table[Data Month])
)

Have a Table chart that contains Data Month, Value, and Total Value Count

I have a case where I need to filter the Data Month to some months only, for example Jan and Feb, and need the Total Value Count to display "2" instead of "12".

Could you let me know the correct formula for my Total Value Count?

Any help will be greatly appreciated! Thank you.

Change ALL to ALLSELECTED:

Total Value Count = 
 CALCULATE(
   COUNT([Value])
   ,ALLSELECTED(Table[Data Month])
 )
