Slider NameError: name ‘pu’ is not defined

Unfortunately, I cannot change it to ‘set each repeat’ because the button is inactive. I cannot click on it. I’m in version 2025.1.1.

What I actually want to achieve is to use the slider, but I run into problems in the newer versions of psychopy. The last version where the slider works how I want it is version 2022.2.4 standalone. It does not work when being in the 2024 version and choosing an earlier version from the setting menu.

As always, thank you for your precious support!
