Here is a work around method
use javascript to store the selected values into a hidden variable before submit. eg. Code:
<input type="hidden" name="FORM_SELECTED_VALUE">
<script>
function sumup(mylist)
{
var selected_value = "";
for (var i=0; i < mylist.options.length; i++)
{
var o = mylist.options[i];
if (o.selected)
{
selected_value += "x" + o.value;
}
}
document.myform.FORM_SELECTED_VALUE = selected_value;
}
</script>
