My Testimonial Slider isn't sliding!

[Meka_Spencer]

I need help! Please!!! So, I cloned someone’s Testimonial slider but for some reason the slider isn’t sliding when I preview the page. Here is a screenshot to show all of the elements for this slider.

[Cloned Site]
(Simple CMS Swiper Slider - Webflow)

The person who created this says it’s built with a slider JS library. Not sure how to find that.

Thank you to whoever can help me!

You’ll probably need to check the published version of the site since Webflow’s preview mode doesn’t handle external code.
