I'm trying to add an image slider to a style and I'm getting an error when I try to add the Javasript. This is what I'm trying to do http://www.w3schools.com/w3css/tryit.as…lideshow_fading . I have added the script below to the footer template, under <!-- JAVASCRIPT_RELOCATE_POSITION -->:
<script data-relocate="true">
var myIndex = 0;
carousel();
function carousel() {
var i;
var x = document.getElementsByClassName("mySlides");
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
myIndex++;
if (myIndex > x.length) {myIndex = 1}
x[myIndex-1].style.display = "block";
setTimeout(carousel, 9000);
}
</script>
The error I'm getting is:
