Why aren't product images showing in my featured slider code?

[WraithAm]

Hello i have been attempting to add a featured slider for my featured collection and i have almost got it from using a code I found on here. However when I add the code everything works besides the images of the products. They don't show up.

This is the link to the code I used.

Any help would be appreciated

Hi @WraithAm 
Dawn theme already supported for the slider function for featured collection section.
You can check section settings in theme customize.

Hey I appreciate the reply I have that selected however the arrow show below the collection instead of to the sides which is what I desire. My website is forwardfurniture.ca and what I want the arrows to look like is how it's set up on the reviews at the bottom of my landing page how the arrows appear and you can scroll.
