cumulative sum based on dates

[Anonymous]

Hello, 

Trying to show a cumulative sum of orders based on Dates (displayed with WeekNum) 

My table Currently looks like this ;

Week Num	Count
1	1
2	4
3	3
4	7

My Future State is 

Week Num	Sum
1	1
2	5
3	8

Thanks!

@Anonymous ,

A new column 

sumx(filter(Table, [Week Num] <= earlier([Week Num])),[count])

A new measure

sumx(filter(allselected(Table), Table[Week Num] <= max(Table[Week Num])),Table[count])
