Move items up and down

Question

I am trying to create the spry based mechanism to move
selected items either up or down. I have drop down and 2 buttobns
up and dwon how can i incorporate this in spry. I have this working
JS. But how about spry.
function Field_up(lst) {
var i = lst.selectedIndex;
if (i>0) Field_swap(lst,i,i-1);
function Field_down(lst) {
var i = lst.selectedIndex;
if (i<lst.length-1) Field_swap(lst,i+1,i);
function Field_swap(lst,i,j) {
var t = '';
t = lst.options
.text; lst.options.text = lst.options[j].text;
lst.options[j].text = t;
t = lst.options
.value; lst.options.value = lst.options[j].value;
lst.options[j].value = t;
t = lst.options
.selected; lst.options.selected = lst.options[j].selected;
lst.options[j].selected = t;
t = lst.options
.defaultSelected; lst.options.defaultSelected =
lst.options[j].defaultSelected; lst.options[j].defaultSelected = t;
function SetFields(lst,lstSave) {
var t;
lstSave.value=""
for (t=0;t<=lst.length-1;t++)
lstSave.value+=String(lst.options[t].value)+",";
if (lstSave.value.length>0)
lstSave.value=lstSave.value.slice(0,-1);
}

What happens when you run it?  Does the drag start?  Does it drop?
If you have a sort applied to the collection you won't be able to rearrange items.
