IF condition in calculate for running total

[Anonymous]

I am using this measure for calculating running total for current month:

RTUmsatz-CM =

VAR currentDay= DAY(TODAY())

RETURN

CALCULATE(

    Umsatz[Umsatz Gesamt]

,'Calendar'[MonthDayNumber]<=currentDay,

FILTER(ALLSELECTED('Calendar'[DateValue]), 'Calendar'[DateValue]<=MAX('Calendar'[DateValue]))

    )

What I want, is that the measure return blank for days we don't have a value. so basically, if today is 17.02, for 18.0 and days after the measure return nothing, instead of the last value of the running total.

so, I want something like this: 

RTUmsatz-CM =

VAR currentDay= DAY(TODAY())

RETURN

CALCULATE(

 IF(  'Calendar'[MonthDayNumber]<=currentDay, Umsatz[Umsatz Gesamt],BLANK())

, FILTER(ALLSELECTED('Calendar'[DateValue]), 'Calendar'[DateValue]<=MAX('Calendar'[DateValue]))

    )

But this return error. Can any one help?

Take a look at this article.  It shows ways to hide future dates when returning calculations.
