Create EBITDA scheme with DAX (Matrix visual)

amitchandak @ amitchandak

I made this in Excel and transfered it to PowerBi. The values without a specifiek measures are 'Direct Sales Stores' and the some rows are with specific measures like 'EBITDA'. 

I tried, after reading the articles, the next: (Amount_rapportering is were the values are, Grootboek[sub] is the table from Excel. 

Poging 1 = 
CALCULATE([Amount_Rapportering], Grootboek[Sub] = "Inkomst")

Poging 2 = 
CALCULATE([Amount_Rapportering], Grootboek[Sub] = "Extra Inkomst")

calculate the Gross Margin

Gross Margin = 
var Inkomst = CALCULATE([Amount_Rapportering], Grootboek[Sub] = "Inkomst")
var Extra   = CALCULATE([Amount_Rapportering], Grootboek[Sub] = "Extra inkomst")

return
Inkomst + Extra

Komop = 
var Currentitem  = SELECTEDVALUE(Blad2[Naam])

return
SWITCH( TRUE(),
    Currentitem = "Gross Margin",DIVIDE([Gross Margin], 1, 0),

calculate ([Amount_Rapportering], 
    FILTER(Blad2, Blad2[Naam] = Currentitem)))

What happend after I use the new measure 'Gross Margin' in the matrix. It didn't work. Any idea why?
