Having problem with the multi-step form buttons

Hi everyone,

I cloned a multi-step form website but “next slide and back” buttons are not working. I deleted and cloned one more time yet still buttons not working.

I review the website and I can see that next and back buttons are in the different positioned from “buttons in the slides” but the real website is working just fine i couldn’t understand it. How can i fix that issue?

Here’s a link for my site.

Thanks for all the help!
