totals per column

Hello,

I need to get the total percentage, but it appears that the values on total is inaccurate.



Here are some measurements that I created:

actual = COUNT('2015_POSdata'[COUNT])

no of stations = CALCULATE(DISTINCTCOUNT('2015_POSdata'[POS-Active Stations]),ALLEXCEPT('2015_POSdata','2015_POSdata'[MonthName]))

monthend day = CALCULATE(DISTINCTCOUNT('2015_POSdata'[DATE]), ALLEXCEPT('2015_POSdata','2015_POSdata'[MonthName]))

expected = '2015_POSdata'[no of stations] * [monthend day]

%age = DIVIDE([actual],[expected])

Kinfly help me please. Thank you.
