problem with openInfoWindowHtml for multiple points

hey

am a beginner and using openInfoWindowHtml to show the balloon text.
my application has an option to show single location and multiple
location.
my single location balloon text works fine using openInfoWindowHtml();
but when i go in for multiple, it always shows the last points text
and the click event for all the points never happends

code snippet:
var markers =[];

for(var i=0;i<(geoList.length)-1;i++){
var geo = (geoList[i]).split(',');
map.setCenter(new GLatLng(geo[3], geo[4]), 2);
var ip_point = new GLatLng(geo[3], geo[4]);

//creating a marker
marker = new GMarker(ip_point);
map.addOverlay(marker);
markers[i] = marker;

// The ballon text which shows the details of the ip address

var ip = "<div style=\"font-family:Verdana,Arial,Helvetica,Sans
Serif;font-size:10px;text-align:left\">";
//var dbName = base64_decode(geo[5]); // added on 14Dec2009
//If IP is not found it goes to else loop
if(geo.length== 9){
ip += "<span class=\"FSColorBold\">"+geo[5]+"</span><br /> ";
ip += "<?php __('IP:'); ?>"+geo[6]+"<br />";
ip += "<?php __('ID:'); ?>"+geo[7]+"<br />";
ip += "<?php __('Last Accessed: '); ?>"+geo[8]+"<br />";
ip += geo[2]+","+geo[1]+"<br />";
}
}
// shows IP details info by default
map.openInfoWindow(map.getCenter(),ip);
// Reloads the IP details info on clicking the marker
GEvent.addListener(marker, "click", function()
{marker.openInfoWindowHtml(ip+'');});

the points are in a loop and the event listeners are outside the
loop.

can anyone tell me exactly wat went wrong.
thanks in advance for the suggestions.
