Newbie - is this a bug

The following HTML code produces the error as given below

     <SCRIPT TYPE="text/javascript">
           <!--
                  if (window.name!="tsrmaster"){
                           document.write("<a href=\"index.htm\"
target=\"_top\">TSR Home     Page</a>")
                 }
            //-->
      </script>
  <noscript>
       <a href="index.htm" target="_top">TSR Home Page</a>
  </noscript>


Line 115, column 75:

       ... ref=\"index.htm\" target=\"_top\">TSR Home Page</a>")
                                                             ^
Is thsi a known problem, is there a fix or a workaround?

I use the validator fromw w3.org, can I load my own copy under W98?
