Compare value by highest selected month

Hi

I need to compare the monthly value with the value of the highest month selected, I'm using the measurements:

MaiorMesSelecionado = CALCULATE( MAX(VENDAS[MES]), ALLSELECTED(VENDAS) )
ValorMaiorMesSelecionado = CALCULATE(SUM(VENDAS[VALOR]),FILTER(VENDAS,VENDAS[MES] = [MaiorMesSelecionado]))

If I set the month 11, everything works

ValorMaiorMesSelecionado = CALCULATE(SUM(VENDAS[VALOR]), FILTER(VENDAS,VENDAS[MES] = 11))

, but when I use the measure of the biggest month, nothing works

this is my report
