.Changeslide functions in preview, but not when published

So I’ve got it set up so that when I click a picture of my team, their bio appears below via .changeslide() - when I hit preview everything works perfectly, but when I publish nothing happens in the live site. anyone have any idea why or what is going on?

Please if anyone can help I really need support here. I cannot for the life of me figure out what I’ve done wrong. I set it up like I have in the past!
