Correct calculation for grand total

[Rai_BI]

Hi, please, someone help me.

I have an issue as below.

How can I adjust the DAX measure below to also calculate the sum for the grand total?

I have the following DAX measure below, it works correctly for each line, but it is not calculating the total value of the grid which is returning empty. I'm trying to use the SUMX function but it's not working to calculate the grand total.

You can download the PBIX file here

Single Measure = 

VAR Seller_1_in_Scope = HASONEFILTER('customer table'[Name Seller1])
VAR Seller_2_in_Scope = HASONEFILTER('customer table'[Name Seller2])

RETURN
SWITCH(
    TRUE(),
    Seller_1_in_Scope && NOT Seller_2_in_Scope, 
    SUMX(
        VALUES('customer table'[Name Seller1]),CALCULATE([Goal Seller 1])),

    Seller_2_in_Scope && NOT Seller_1_in_Scope, 
    SUMX(
        VALUES('customer table'[Name Seller2]),CALCULATE([Goal Seller 2])),

    Seller_1_in_Scope && Seller_2_in_Scope, 
    SUMX(
        SUMMARIZE(
            'customer table',
            'customer table'[Name Seller1],'customer table'[Name Seller2]),
            CALCULATE([Goal Seller 1] + [Goal Seller 2])
)
)

Try this 

Single Measure = [Goal Seller 1] + [Goal Seller 2]
