Thumb_List Scroll not working

[Shanemiah]

Hi 

 

I have been trying to find out why thumb_list scroll don't work, Some products i have 5-10 images, and when i click the scroll button it disappears after clicking it like its scrolling, but images don't scroll. 

 

I had previously changed product.css and product.js to the old one but for main reasons, it breaks the website but it also had working scroll bars for a brief moment until the website crashes, so i had to revert the change. I have looked into the coding on both but nothing has seemed to change. 

 

Does anyone know why this wouldn't be working ? 

 

Kind Regard
