Help for expression date-2

[#1]

Hello, I have another problem when I write

sum({<AnnéeMois = {'$(=monthname(AddMonths([Date Calendrier],-2)))'}>} Vol_Appels)   in expression, it shows me 0 in result.

Can you help me please? thx

to know what is issue, you have to share Sample data.

Because Output is not null '-' , it is '0', it means expression is correct,.
