oznacit <select> pri submit

ako spravim aby pri stlaceni tlacitka submit vo formulari, oznacilo cely <select> a odoslalo formular

nejako to nefunguje mozno preto, lebo toho tam mam viac...
mam 2 multi-selecty , vlavo je multiselect zoznam poloziek a presuvam to do praveho multiselectu, potom ked je vsetko vybrane potrebujem aby pri stlaceni tlacitka submit oznacilo cely pravy multiselect a odoslalo formular
Tu je moj kod.

<script language="JavaScript">

function selectAllOptions(obj) {
for (var i=0; i<obj.options.length; i++) {
obj.options[i].selected = true;
}
}


function addOption(theSel, theText, theValue)
{
var newOpt = new Option(theText, theValue);
var selLength = theSel.length;
theSel.options[selLength] = newOpt;
}


function deleteOption(theSel, theIndex)
{ var selLength = theSel.length;
if(selLength>0)
{theSel.options[theIndex] = null;}
}

function moveOptions(theSelFrom, theSelTo)
{ var selLength = theSelFrom.length;
var selectedText = new Array();
var selectedValues = new Array();
var selectedCount = 0;
var i;


for(i=selLength-1; i>=0; i--)
{
if(theSelFrom.options[i].selected)
{
selectedText[selectedCount] = theSelFrom.options[i].text;
selectedValues[selectedCount] = theSelFrom.options[i].value;
deleteOption(theSelFrom, i);
selectedCount++;

}

}

for(i=selectedCount-1; i>=0; i--)
{
addOption(theSelTo, selectedText[i], selectedValues[i]);
}

}
