Yes, the field name is missing. If you need to check the current field to contain a "," you can use the self operator

nicht(enthält({Self}, ","))

If you need to check another field (or if you want to name the field instead of using self operator, you can just use the field to check by grabbing it from the collection of named controls / "Benannte Steuerelemente"

nicht(enthält(Feldname, ","))

Strange. I can reproduce your issue but have no time for it now to investigate it more. To be continued...

The following seems to work (control settings):

I still do not know why the not(contains(...,...) does not work. It works perfectly with a semi-colon.

It is working for me 

Hi Jakob Putz‌,

Ok. I must have been not that clear yesterday  not(contains({Self}, ",")) works indeed as expected.

What I noticed, is that your {Self} is not red. You probably typed it instead of selecting it from 'Named Controls'. This is probably your issue.

Cheers,

Rick
