Aggregation to avoid accounting twice

Thank you so much for your help!

It almost works, but it does not when I select different dates at the same time. Selecting more days creates conflict. 

When selecting Spain & Italy days 1 & 2, the result should be

Day 1: 50+40

Day 2: 12+5

Result: 90+17=107

However, the "Card plot" says "MdxScript(Model) (3,70) Calculation error in measure 'Table1[Measure]: A table of multiple values was supplied where a single value was expected"

Thank you so much again!

HI antonioaceituno

Try this revised MEASURE

Measure =
SUMX (
    SUMMARIZE ( ALLSELECTED ( Table1 ), Table1[Country], Table1[Date] ),
    CALCULATE ( DISTINCT ( Table1[Daily Target] ) )
)
