urgent explination?

[Anonymous]

sum({<month={'*'}>}sales)

what it gives ?  8 is for ignoring all?

or all selection?

[Anonymous]

In this case will bring all selections of the field month.

To ignore selections, use just month=

month={'*'} means that the expression will take all month values that are not null into consideration even if the user selected specific months. The user selection of the month field is ignored by the expression.
