Show and hide on click not working

Hey everyone, I’m new to webflow and am fiddeling around with interactions. Specifically with show and hide on click. I followed this tutorial exactly.

Unfortunately, that does not work. I’m using a button as the trigger and a paragraph that interacts with it. Can anyone give me some advise?

Cheers Fou
