In running total add by ascending by values

[xRTP]

Hello, 

I need help on cumulative running total, it adds on acsending order (alphabetical order) base on column test

The thing is i want to add first is the biggest number down to the lowest under # Errors column

Here's the code i've tried:

TestCumulative =

var currenterrors =

calculate( sum( 'Raw'[test]) )

return

calculate(

sumx(

filter( 'Raw', 'Raw'[Errors]  >= currenterrors ),

'Raw'[Errors]),

all('Raw'[Test]

))

But it show's this 

Note: All 3 columns are just 1 column, 1st column is Test, 2nd column is count of Test and third is the Cumulative of Test.

Appreciate your answers!
