i have these two select boxes that filter the first item in a line into the first box and the second into the second box and i was wanting a delete and copy button that would delete or copy the selected item from a box... here is my code:

<HTML>
<HEAD>

<script type="text/javascript" language="javascript">

function makeList(oIframe) {
var textarr, IFbody = oIframe.document.getElementsByTagName('body').item(0).innerText;
if (IFbody == '') return;
textarr = IFbody.replace(/<\/?xmp>/gi, '').replace(/ \- /g, ' ').split(/\s+/);
var newopt, oSelect1 = document.f.dynamic1, oSelect2 = document.f.dynamic2;
var txtlen, colons = '::::::::::::::::::::::::::::::';
oSelect1.length = oSelect2.length = 0;
oSelect1.options[0] = new Option;
oSelect2.options[0] = new Option;
for (var o=0; o<textarr.length; o+=2) {
txtlen = textarr[o].length;
newopt = new Option('' + textarr[o] + '',textarr[o]);
oSelect1.options[oSelect1.options.length] = newopt;
newopt.className = 'space';
txtlen = textarr[o+1].length;
newopt = new Option('' + textarr[o+1] + '',textarr[o]);
oSelect2.options[oSelect2.options.length] = newopt;
newopt.className = 'space';
}
}

function file_select(oFileUpload) {
var oForm = oFileUpload.form;
oForm.action = oFileUpload.value;
oForm.sub.style.visibility = 'visible';
oForm.start.style.visibility = 'hidden';
}

</script>

</HEAD>
<BODY>

<form name="f" target="loader">

<input type="file" name="txtfile" style="position:absolute;top:-100px;" onchange="file_select(this)">
<input type="button" name="start" value="Browse..." onclick="txtfile.click()">
