DAX counting rows that are filterd by a slicer

[abap32]

Hello there,

i have a month slicer witch uses the value MonthID and looks like this: 

I also have a measure: 
myMeasure= CALCULATE(
IF (
(COUNT ( table.column1 )) = BLANK (), 0 ,
(COUNT ( table.column1] )))
)

I want to change the code of the measure to only count rows inside the chosen date range. 

Could you please help me? Thank you

Without seeing your tables/fields this is my best guess:

= CALCULATE(
COUNT(table.column1
             ),
ALLEXCEPT('MonthIDtable','table'[MonthID]
                   ),
ISBLANK(table.column1
               )<>TRUE()
)

Thank you very much for your answer cthurston, but i need a date range and not to exclude only one month with the ALLEXCEPT function. That didnt work for me unfortunatelly.
