JavaScript Carousel and Custom Scrollbar Combined with Mouse Wheel Sharing Code Snippet

This is a carousel I made myself, you can take a look, I haven't optimized it yet. Any suggestions for improvement can be discussed privately

You figure out the layout yourself

<div class="slider" id="circle">
<a href=""><img src="img}}/6p.jpg" alt="" /></a>
`
<ul class="circle" >
<li onclick="lun(1)" id="ico1">1</li>
<li onclick="lun(2)" id="ico2">2</li>
<li onclick="lun(3)" id="ico3">3</li>
<li onclick="lun(4)" id="ico4">4</li>
<li onclick="lun(5)" id="ico5">5</li>
<li class="current" onclick="lun(6)" id="ico6">6</li>
</ul>
<div class="arrow">
<a href="javaScript:;" class="arrow-l" onclick="bo2()" id="bo1"><</a>
<a href="javaScript:;" class="arrow-r" onclick="bo1()" id="bo2">></a>
</div>
</div>
<script>
var c = 0 ;
var t ;
window.onload = function () {
t = setInterval("bo1()",5000);
}
function lun(num){
c = num ;
var ptn = document.getElementById("circle").getElementsByTagName("img")[0];
for (var i = 1 ; i < 7;i++ ) {
var li = document.getElementById("circle").getElementsByTagName("li")[i-1];
li.style.backgroundColor = "#3E3E3E";
if (num == i) {
ptn.src = "img/"+ i + "p.jpg";
li.style.backgroundColor = "#B61B1F";
}
}
}
function bo1() {
if(c>=6{
c = 0 ;
}
c++;
lun(c);
}
function bo2() {
if(c<=1{
c = 7 ;
}
c--;
lun(c);
}
</script>

Let's see the custom scrollbar combined with mouse wheel DEMO below
