Hello Everyone

I’m the new NUB in town lol, and I don’t know much about coding and I needed help finding or creating a Jquery horizontal mouse scroll. I tried following these step from this tutorial but I don’t know what the next step is afterwards. I would gladly appreciate it if anyone could help. here’s the link to the website I want to add the Jquery to http://franckyade.com/index.php/fashion-2/

Thanks All
