Javascript error

[ecannizzo]

Here is my script I'm using:

<script language=&quot;Javascript&quot;>
var IE4 = (document.all && !document.getElementById) ? true : false;
var NS4 = (document.layers) ? true : false;
var IE5 = (document.all && document.getElementById) ? true : false;
var N6 = (document.getElementById && !document.all) ? true : false;


if (IE5 == false) or (N6 == false)
{window.location=&quot;index.asp?SSID=&quot; + &quot;<%=request(&quot;SSID&quot%>&quot;}
</script>

**********Now the problem********

In IE 4.0, I get a javascript error line 12. In Netscape 6, it tells me it can't find the script. It works fine in IE 5.5 and Netscape 4.76. Any ideas?

Thanks!
