DAX: How to correctly create a measure group from a range of dates?

Question

I am using data that exactly looks like this:

DATE       | VALUE
01/01/2011 | 100
02/01/2011 | 150
02/01/2011 | 550       

I want calculated measure with values within a date range with DAX Syntax

consuntivo = CALCULATE(SUM(provadat[valori]);provadat[datazione]>=DATE(2015;01;01)&&provadat[datazione]<=DATE(2016;01;01))  

But i am getting which i am not expecting

So any help regrading it? 

Answer 1

Use this DAX expression

consuntivo = SUM(provadat[valori])
