Hi
I want to use this script to display a floating message that follows page scrolling, but I need it to start only when the user scrolls down to a specific potion of the page. The reason is that I have banner ads at top, occupying all the area above the fold, so I want this area clear, and the floating message (its a message for guests to register in my forum) to show starting from after that.

What code should I add to do so please?

Here is the script that I'm using:

<style type="text/css">

#topbar{
position:absolute;
border: 1px solid black;
padding: 2px;
background-color: lightyellow;
width: 620px;
visibility: hidden;
z-index: 100;
}

</style>

<script type="text/javascript">

var persistclose=0 //set to 0 or 1. 1 means once the bar is manually closed, it will remain closed for browser session
var startX = 80 //set x offset of bar in pixels
var startY = 50 //set y offset of bar in pixels
var verticalpos="frombottom" //enter "fromtop" or "frombottom"

function iecompattest(){
return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}

function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
if (offset != -1) {
offset += search.length
end = document.cookie.indexOf(";", offset);
if (end == -1) end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}

function closebar(){
if (persistclose)
document.cookie="remainclosed=1"
document.getElementById("topbar").style.visibility="hidden"
}

function staticbar(){
	barheight=document.getElementById("topbar").offsetHeight
	var ns = (navigator.appName.indexOf("Netscape") != -1) || window.opera;
	var d = document;
	function ml(id){
		var el=d.getElementById(id);
		if (!persistclose || persistclose && get_cookie("remainclosed")=="")
		el.style.visibility="visible"
		if(d.layers)el.style=el;
		el.sP=function(x,y){this.style.left=x+"px";this.style.top=y+"px";};
		el.x = startX;
		if (verticalpos=="fromtop")
		el.y = startY;
		else{
		el.y = ns ? pageYOffset + innerHeight : iecompattest().scrollTop + iecompattest().clientHeight;
		el.y -= startY;
		}
		return el;
	}
	window.stayTopLeft=function(){
		if (verticalpos=="fromtop"){
		var pY = ns ? pageYOffset : iecompattest().scrollTop;
		ftlObj.y += (pY + startY - ftlObj.y)/8;
		}
		else{
		var pY = ns ? pageYOffset + innerHeight - barheight: iecompattest().scrollTop + iecompattest().clientHeight - barheight;
		ftlObj.y += (pY - startY - ftlObj.y)/8;
		}
		ftlObj.sP(ftlObj.x, ftlObj.y);
		setTimeout("stayTopLeft()", 10);
	}
	ftlObj = ml("topbar");
	stayTopLeft();
}

if (window.addEventListener)
window.addEventListener("load", staticbar, false)
else if (window.attachEvent)
window.attachEvent("onload", staticbar)
else if (document.getElementById)
window.onload=staticbar
</script>

<div id="topbar">
<a href="" onClick="closebar(); return false"></a>
Your content here.
</div>

this is a complete alternate to the attempt, but maybe put it in two sperate pages, and frame them, then you can have the bottom scroll and still allow the advertisement banners to show...

Thanks, but I don't want to use frames.
Isn't there an event or something to use as a condition upon which the floating box starts to show up?
