Cumulative Sales amount beetween 2 dates

Hello Guys, 

Hi guys, I hope you're all well! I'm currently creating a Sales Commission Dashboard, and I'm running into an issue that I need your help with (Thanks in advance).
I was also inspired by this tutorial https://www.youtube.com/watch?v=9hGowlw4YPc

I have a commission percentage table associated with a validity period and a range of amounts.

I create 2 mesures 

CloseDate range min = 
var closedate= SELECTEDVALUE(Opportunity[CloseDate])
var currentsale= SELECTEDVALUE(Opportunity[OwnerId])
return
CALCULATE(
    max('Données comissions'[Effective From]),
    FILTER(
        'Données comissions',
        'Données comissions'[Effective From]<=closedate&&'Données comissions'[Effective To]>=closedate&&'Données comissions'[Sales ID]=currentsale
    )
)

which gives the minimum date of the period in which we are located. We do the same with the maximum date in the measurement

Cumulative Sales = 
var selectedCustomer = SELECTEDVALUE(Opportunity[OwnerId])
RETURN
IF(
    ISBLANK([CloseDate range min]) || 
    ISBLANK([CloseDate range max]), 
    BLANK(),
    CALCULATE(
        SUM(Opportunity[Amount]),
        FILTER(
            ALL(Opportunity),
            Opportunity[OwnerId] = selectedCustomer &&
            Opportunity[CloseDate] >= [CloseDate range min] &&
            Opportunity[CloseDate] <= MAX(Opportunity[CloseDate])
        )
    )
)

This the result that i have 

And i do not understand why the formula do not calculate the good amount 
Can someone help me pls ?
