Problem with a Set Analysis

[Anonymous]

Hi, I have a question with a set analysis.
I have two analyzes to do on a sum, I have to add the income in one period.
For this I made the following formula
=SUM({$<[DESC_GRUPO_B] = {INGRESOS},MES={$(=only(vMes))}>}IMPORTE)*-1
In this case "vPeriodo" is a variable that I bring from the scrip, even if it can be taken out by formula would be better.
But I do not know what can be wrong that is not correctly performing the sum, it says 0.
I hope you can help me.

May be try

SUM({$<[DESC_GRUPO_B] = {'INGRESOS'}, MES={"$(vMes)"}>}IMPORTE)*-1
