Using Selected Value when 2 Years are selected in Filter?

[kressb]

I have a table like this:

I have a slicer.

As long as I keep the slicer to single select, this Measure retrieves the correct result:

Measure = calculate(

                                   sum(DateDimension[Denominator]),

                                           FILTER(DateDimension,DateDimension[Date]<=

                                                      Calculate(

                                                                      MAX(NumberTable[EOMonth].[Date]),

                                                                     Filter(NumberTable,NumberTable[CalendarYear]                     

                                                                     =SELECTEDVALUE(DateDimension[Year]))

                                                                              )

                                                 ))

But I want to change it so that if the slicer is All or multiple years, it will still work:

What am I missing?

TYIA.

@kressb You can't use SELECTEDVALUE when there is more than one value, otherwise it will return the "alternate result". You need to get the values using VALUES or DISTINCT and use the IN operator.
