Disable Parallax Scrolling on Mobile

Hello,

I am working on a website. It looks great on the desktop, but once it goes to mobile, the parallax scrolling effect is changed. All of the images repeat themselves on the mobile and tablet versions of the website, but I’d like them to be fixed in place with no repeat. I have tried using some of the code I have found through Google, but nothing seems to be working.

Thanks for the help.
