Sry for the delayed answer. Not recognize means that qlik sense doesn't Show the Expression as fine (e.g. the "$" is normaly shown blue when the Expression is fine, but not in this Expression). You know what I mean?
So I think there are some missing quotes in the Expression, but im not sure..
That is a misconception that you might have... I would suggest you to try the expression and click okay to see if you get what you need... just because syntax editor is not showing right colors, doesn't really mean that expression is incorrect .
With an Expression it still doesnt work , but I do it now manually by clicking the most current Problem instead to write it in a Expression.
Anyway, Thanks for your help!
Unfortunately I can't upload Pictures or something else from my Company Computer but It's simple: Just 2 Pie Chart- 1 Pie Chart Shows "Problem" other "Reaction". So most often Problem is for example Credit Card. So I click on credit Card in the pie Chart and then it shows me all reactions to this Topic. So instead that this process goes by an Expression I have to click myself.
