General Settings help

Hi Team

I am a learner and I am trying to add infinite scrolling in my website. However, I think I have been missing something further to have the scrolling activated.

I have added the selectors under plugin General Settings as attached screenshot https://jinlongmart.com/wp-content/uploads/2016/04/Screenshot-24.png

My website name is jinlongmart.com can someone please advise what went wrong with my settings. please team
