<script language=JavaScript>
var posX, posY;
var ie    = document.all?1:0;
var ns    = document.layers?1:0;
var dom   = document.getElementById?1:0;
var dhtml = new svetLayer("sampleLayer");
var path  = new Array(452,278,452,278,452,278,452,278,452,278,452,278,452,278,452,278,452,278,452,278,452,278,452,278,452,278);
var index = 0;
var trNum = 0;
function svetLayer(id)
	{
		this.name = dom?document.getElementById(id):ie?document.all[id]:ns?document.layers[id]:null;
		if (this.name !== null)
			{
				this.css    = (dom||ie)?this.name.style:this.name;
				this.x      = dom?this.css.pixelLeft:ie?parseInt(this.css.left):this.css.left;
				this.y      = dom?this.css.pixelTop:ie?parseInt(this.css.top):this.css.top;
				this.moveTo = moveTo;
				return this;
			}
