Qliksense Ranking TOP 20% and top 20

[beginner91]

Hello guys,

iam new here and try to learn Qlik sense.

I tried to rank up the "Anzahl Fehlerbilder" in top 20% or maybe top 20. Its a indicator and its counted.

I tried to figure it out myself but i didnt work. It would be nice of someone can help me.

It would be nice to tell me what exactly what to do.

Thank you very much.
