Use of TREATAS

[PaulMoses]

Hello there
Can you please tell me if I use TREATAS correctly?
From the tables in the picture, I would like to create a "Total Amount" column in table "TABLE_DIM_SLICER_DAO", with the total amount of each DAO, using TREATAS. But it's the total amount of the entire column that appears. I do not know why, despite all my checks.
I use this simple DAX formula : 

TotalAmount = 
CALCULATE(SUM(FACT_PAR_DETAIL_REFDATE[LOAN_CNTRT_AMT]); TREATAS(VALUES(DIM_DAO[DAO_NAME]); Table_Dim_Slicer_DAO[DAO_NAME]))

Your help will be extremely valuable.
Thank you

@PaulMoses

Try with this one

TotalAmount =
CALCULATE (
    SUM ( FACT_PAR_DETAIL_REFDATE[LOAN_CNTRT_AMT] ),
    TREATAS ( { Table_Dim_Slicer_DAO[DAO_NAME] }, DIM_DAO[DAO_NAME] )
)
