I'm trying to add something like this: https://onepiece.fandom.com/wiki/Template:Slider?useskin=oasis to the wiki home page but I can't seem to make it work properly. I've even tried just copying and pasting everything directly from the one piece wiki and it still doesn't work. https://re-monster.fandom.com/wiki/Template:Slider?useskin=oasis. I have also copied the pages mentioned in the slider generator template documentation. I dont know what im doimg wrong. Any help is appreciated. Thank you
