Set analysis intersection between previous excluded and current selection

[#1]

Hello,

I need to check if the current selection is part of the excluded selection of the previous selection.

Maybe with set analysis ?

I tried the following

  = Count({1-$1 * $} Field) > 0

an intersection between the previous excluded selection {1-$1} and the current selection {$}.

You're are just missing a parenthesis:

count({(1-$1) *$} Field)
