I have a problem, when the image is clicked, the link3 value (which is correct) is displayed on the screen instead of it going to that page!! Can someone tell me what the problem is?

in head:
	var link3;
	var jack;
	var position;

<script language="JavaScript" type="text/javascript" src="/clf02/scripts/browser.js"></script>

<script language="JavaScript">
link3 = window_onload();
function window_onload()
	var link2;
	link2 = parent.location.href;
	alert("The address of the parent frame is " + link2);
	position = link2.lastIndexOf("-");
	link3 = link2.substring(0, position) + "e.html";
	return link3;
in body:
<body language=JavaScript bgcolor="#FFFFFF">
<a href="javascript: window_onload()"><span lang="fr"> <img src="../images/nav1st_level_lang-e.gif" width="89" height="14" vspace="0" hspace="0" border="0" alt="Fran&ccedil;ais"></span></a>
