Custom checkbox's + showing hidden divs

[xXREDXIIIXx]

Im a gomplete newbie here. so please be gentle.

 

I dont claim any of the JS below as my own

 

I can get the code to work if I dont use my own custom images.

 

function showMe(id){ var obj = document.getElementById(id);
  if (obj.style.display == "none"){obj.style.display = "inherit";}
  else {obj.style.display = "none";}
}

<input class="styled" name="foo" type="checkbox" id="foo" value="1" onclick="showMe('div1')" />
<input class="styled" name="bar" type="checkbox" id="bar" value="1" onclick="showMe('div2')" />
<div id='div1' style="display:none;">
<div id='div2' style="display:none;">

var checkboxHeight = "14";
var radioHeight = "14";
var selectWidth = "190";

document.write('<style type="text/css">input.styled { display: none; } select.styled { position: relative; width: ' + selectWidth + 'px; opacity: 0; filter: alpha(opacity=0); z-index: 5; } .disabled { opacity: 0.5; filter: alpha(opacity=50); }</style>');

var Custom = {
init: function() {
	var inputs = document.getElementsByTagName("input"), span = Array(), textnode, option, active;
	for(a = 0; a < inputs.length; a++) {
		if((inputs[a].type == "checkbox" || inputs[a].type == "radio") && inputs[a].className == "styled") {
			span[a] = document.createElement("span");
			span[a].className = inputs[a].type;

			if(inputs[a].checked == true) {
				if(inputs[a].type == "checkbox") {
					position = "0 -" + (checkboxHeight*2) + "px";
					span[a].style.top = position;
				} else {
					position = "0 -" + (radioHeight*2) + "px";
					span[a].style.backgroundPosition = position;
				}
			}
			inputs[a].parentNode.insertBefore(span[a], inputs[a]);
			inputs[a].onchange = Custom.clear;
			if(!inputs[a].getAttribute("disabled")) {
				span[a].onmousedown = Custom.pushed;
				span[a].onmouseup = Custom.check;
			} else {
				span[a].className = span[a].className += " disabled";
			}
		}
	}
	inputs = document.getElementsByTagName("select");
	for(a = 0; a < inputs.length; a++) {
		if(inputs[a].className == "styled") {
			option = inputs[a].getElementsByTagName("option");
			active = option[0].childNodes[0].nodeValue;
			textnode = document.createTextNode(active);

				}
			}
			span[a] = document.createElement("span");
			span[a].className = "select";
			span[a].id = "select" + inputs[a].name;
			span[a].appendChild(textnode);
			inputs[a].parentNode.insertBefore(span[a], inputs[a]);
			if(!inputs[a].getAttribute("disabled")) {
				inputs[a].onchange = Custom.choose;
			} else {
				inputs[a].previousSibling.className = inputs[a].previousSibling.className += " disabled";
			}
		}
	}
	document.onmouseup = Custom.clear;
