I have a  problem when I access the page in IE6. This worked fine with 
previous versions of IE. I might better show part of the code, so that it 
will be easier to understand

var wPopupNavigate;

function showPopupNavigate(sEmplID, sBalDate) {
//Display the window, and fill it with html elements.
var sHTML;
var d;
var sOpenParm;
var dBalDate = new Date(sBalDate);	
var arRole;
var x;
var y;
var nWinHeight = 325;

	//Make sure it only displays once
	if (wPopupNavigate) { ** error when trying to check the 
wPopupNavigate variable **
	alert(sEmplID);
		if (!wPopupNavigate.closed) { 
			wPopupNavigate.close();
		}
	}

My error logger says the object is undefined and breakd here
This code worked worked fine with all the previous versions of IE and 
latest version of Netscape. Please help

Thanks
