         if (n > x.length) { slideIndex = 1 }
         if (n < 1) { slideIndex = x.length }
         for (i = 0; i < x.length; i++) {
             x[i].style.display = "none";
         }
         for (i = 0; i < dots.length; i++) {
             dots[i].className = dots[i].className.replace(" w3-white", "");

Hi,

What do you see when using "view source" in your browser for your onclick event?
