Details

An object created in javascript code gets a "has no properties" error when the 
focus() method is used.

The following line:

frm.frmLeagues.focus();

in the following code causes the error:

<html>

<head>
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<meta name="GENERATOR" content="Microsoft FrontPage 5.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<title>NITTL Standings</title>

<script LANGUAGE="JavaScript" FOR="window" EVENT="onLoad()">
<!--
	var frm = new Object();
	frm = document.formLeagueList;
	frm.frmLeagues.focus();
//-->
</script>

</head>

<body bgcolor="#C0C0C0">
Despite Microsoft's claim in
http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/htmlfor_0.asp
that

<script LANGUAGE="JavaScript" FOR="window" EVENT="onLoad()">

is defined in the DOM Level 2 spec as saying the script contents should be
assigned to the window.onload, it ain't. The htmlFor property was reserved for
future use, and that's it, and in every browser on Earth except IE, that script
will run inline, as soon as the <head> is parsed, and fail because the form
hasn't been seen yet, or just won't run at all. Put that script in a function,
call the function from <body onload="">, and it will work fine in everything.
