Trial and more error
I'm using the following javascript along with the scriptaculous.js and prototype.js:

<script type="text/javascript">
function updateOrder(){
var options = {
method : 'post',
parameters : Sortable.serialize('firstlist')
};
new Ajax.Request('g2.pl', options);
}
Sortable.create('firstlist', {constraint:'vertical', onUpdate : updateOrder});
</script>

What would be the variable names getting passed through the post method? Seems no matter what I try I can't get the variable values returned.
