Slider not working

I have been trying to build a slider of three images at the bottom of the home page of my website.

Every time I put the short code in, the preview works perfectly, but once on the site, the images show stacked on top of each other and don’t slide.

This page is live so I have had to remove the code until I can get it to work. Any help in getting this up would be appreciated.
