Ajax Field doesn't work.

The Ajax statement does not work. I configured it as specified in the Instructioninstruction .
If I turn it off, the filtering in the form works after reloading.
I have no idea what could be done differently, the instruction does not allow any other options.

I'd really like to help you, but I can't by lack of information and telepathy skills

Please be more precise than "The Ajax statement does not work".

1- What exact "Ajax statement" ?
2- What exactly "does not work" ?
3- What exactly do you want to achieve ?
4- What is exactly your configuration (configuration screen-dumps are welcome) ?

Please understand that to help you we need to understand:
a- what you want to do, and
b- how you tried to do it, so that
c- we can if needed reproduce your setting on our development test installation.

Sorry that I was and am so imprecise. The project for which it was intended is initially on hold.

No worries, do you still need help to get the ajax to work for your case ?
How can we help you ?

Thank you for your help, but now it's vacation time. If you want to see the result on www.karate-paderborn.de/corona-trainingsplan/corona-trainingsplan you can find it.
I once sent Krileon a login.

For a fields profile edit display to update on another fields value changing you need to use the Update On functionality provided by CB Core Fields Ajax. I've retested this behavior as working fine. I assume your configuration is incorrect somewhere and you'd need to provide screenshots of what you configured in those fields.
