Matrix - Calculation inside a matrix

Thank you Anonymous for your help I know it's hard without a real data sample but none of the 2 last measures give me what I'm expected.

Maybe that's gonna help.

What I want is to divide the number of "association" with a payment by the number of "valid association"

Here my 2 measure for that

avec Paiement = 
CALCULATE (
    COUNTROWS ( Associations ),
    FILTER(
        Associations,
        Associations[first_payment_date] <> BLANK ()
    ),
    FILTER (
        Associations,
        Associations[state] = "Publiee"
            || Associations[state] = "GrosseAssociation"
            || Associations[state] = "AttentePublication"
    )
)

Inscrites Valides = 
CALCULATE (
    COUNTROWS ( Associations ),
    FILTER (
        Associations,
        Associations[state] = "Publiee"
            || Associations[state] = "GrosseAssociation"
            || Associations[state] = "AttentePublication"
    )
)

When I add a simple "DIVIDE()" of those 2 and I add it as a card I got the correct answer but if I had this measure into the matrix I got 100%.

I also tried w/o success something like :

MonthPercentage = DIVIDE(
    Associations[avec Paiement],
    CALCULATE(
        Associations[Inscrites Valides],
        FILTER ( 'Date', 'Date'[Date] >= MAX ( 'Date'[Date] ) && 'Date'[Date] <= MAX ( 'Date'[Date] ) )
    ),
    0)

 EDIT :
Looking around I think this is something like this that I want to acheive :

Anonymous It's weird I just posted an answer but I cannot find it in the thread...

Ok so sorry but I understand what you are trying to do but it doesn't work here.

I try to dig deeper to understand why a simple division of two differents values gives me 100% in my matrix.

So I added in a matrix the 2 calculations I have made as a value

CALCULATE (
    COUNTROWS ( Associations ),
    FILTER(
        Associations,
        Associations[first_payment_date] <> BLANK ()
    ),
    FILTER (
        Associations,
        Associations[state] = "Publiee"
            || Associations[state] = "GrosseAssociation"
            || Associations[state] = "AttentePublication"
    )
)

---

Inscrites Valides = 
CALCULATE (
    COUNTROWS ( Associations ),
    FILTER (
        Associations,
        Associations[state] = "Publiee"
            || Associations[state] = "GrosseAssociation"
            || Associations[state] = "AttentePublication"
    )
)

There is now way that both can have the same value at the end since I'm adding a second FILTER to the first measure.

But this is what I got :
