How do I do this? So when someone clicks on a link in the drop down menu, how will it target to my iframe?

The code I have is:

<script language="javascript">
function jump(form) {
var myindex=form.menu.selectedIndex
if (form.menu.options[myindex].value != "0")
{
window.open(form.menu.options[myindex].value,
target="iframe");
}
}
//-->
</script>

<form name="lissamenu2">
<select name="menu" style="background-color: #FFFFFF;
font size=10 ; font-family: verdana; color:#000000"
size="1" onchange="jump(this.form)">

<option value="0">Navigate</option>
<option value="0"></option>
<option value="iframe.html">Main</option>
<option value="etc.html">Etc.</option>
<option value="fan.html">Fan</option>
<option value="humor.html">Humor</option>
<option value="info.html">Info</option>
<option value="interact.html">Interact</option>
<option value="media.html">Media</option>
<option value="misc.html">Misc.</option>
<option value="www.html">WWW</option>



</select>
</form>

Any ideas? Thanks if you can help! :D
