Buttons aren't working when pressed

I am working with a template.

The buttons (next and previous) on the home page to show testimonials don’t work when I press them.

Thank you for your future help.

hi @Andrej_Torok this interaction is triggered by JS that is applied in page settings. Be aware that JS is not running in designer mode. To see JS interactions (prev - next) you have to publish your changes and preview live page.

So when I publish the website it should work?

hi @Andrej_Torok did you try it?

I will, just need to finish making it.

Just to be clear, the publishing means saving changes and preview website on webflow.io domain.
