Hvor skal javascriptet placeres?

Hej Jeg har et problem med et javascript der skal redirecte når brugeren ikke flash installeret. Please check om denne fil er korrekt?

<HTML>
<SCRIPT LANGUAGE=\"JavaScript\">
<!--
function detectflash()
{


    flashpage    = \"index.html\"
    nonflashpage    = \"/start/index2.htm\"
    cantdetectpage    = \"unabletodetectflash.html\"

    noautoinstall = \"\"

    if(navigator.appName == \"Microsoft Internet Explorer\" &&
        (navigator.appVersion.indexOf(\"Mac\") != -1 ||
        navigator.appVersion.indexOf(\"3.1\") != -1)){
            noautoinstall = \"true\";
    }

    if (navigator.appName == \"Microsoft Internet Explorer\" && noautoinstall != \"true\")
    {
        window.location=flashpage;
    }
    else if(navigator.plugins)
    {
        if(navigator.plugins[\"Shockwave Flash\"] || navigator.plugins[\"Shockwave Flash 2.0\"])
        {
            window.location=flashpage;
        }
        else
        {
            window.location=nonflashpage;
        }
    }
    else
    {
    window.location=cantdetectpage;
    }
}
