Layer i NS virker af h...... til

Nu har jeg siddet og prøvet at få en side til at vise en anden side inde i en tabel, men det virker selvfølgelig ikke i NS.... Hvad gør jeg galt?

<html>
<head>
<title>Layer</title>

<script language="JavaScript">
<!--

ns4 = (document.layers)? true:false
ie4 = (document.all)? true:false

function load(page) {
    if (ns4) document.textLayer.src = page
    else if (ie4) parent.textFrame.document.location = page
}

//-->
</SCRIPT>

<STYLE TYPE="text/css">    <!--

    #textLayer {
        /*position:absolute;
        top:120px;
        left:50px;
        float:right;*/
        position:relative;
        include-source:url("skrift.htm");
        width:164px;
        z-index : 1;
    }
    -->
</STYLE>

</head>


<body bgcolor="#ffffff" topmargin="0" leftmargin="0" marginwidth="0" marginheight="0">

<table width="100%" border="0" cellspacing="0" cellpadding="0" bgcolor="#ffffff">
