Dropdownmeny - Target?

Hvor legger jeg inn target-taggen i dette scriptet?

<SCRIPT LANGUAGE=\"JavaScript\">
function selectaplace(form) {
var appname= navigator.appName;
var appversion=parseInt(navigator.appVersion);
if (appname == \"Netscape\" && appversion >= 3) {
var formindex=form.select1.selectedIndex;
var storage=form.select1.options[formindex].text;
if (form.select1.options[formindex].value != \"none\") {
var msg=storage+\"You are now being transferred to the -> \"+storage;
for (var spot=0;spot<msg.length-storage.length;spot++) {
var x=msg.substring(spot,msg.length);
form.select1.options[formindex].text=x;
for(var d=0;d<150;d++) { };
}
window.location=form.select1.options[formindex].value;
form.select1[formindex].text=storage;
} else  {
form.select1[formindex].text=\"Not a real option!\";
for(var d=0;d<1250;d++) { };
form.select1[formindex].text=storage;
  }
}
else {
var formindex=form.select1.selectedIndex;
window.location=form.select1.options[formindex].value;
  }
}
function makeMyMenu() {
document.write (\'<form><select name=\"select1\" onChange=\"selectaplace(this.form)\" size=1>\');
document.write (\'<option value=../reklame.htm#Topp>Til toppen\');
document.write (\'<option value=../reklame.htm#Biler>Biler\');
document.write (\'<option value=../reklame.htm#Spedisjon>Spedisjon/Shipping\');
document.write (\'</select>\');
document.write (\'</form>\');
}
makeMyMenu();

// End -->
</SCRIPT>
