Hello!
You can do it in many ways:
1. Create an empty placeholder for hidden input (div at the bottom of your
form). You can then easily replace content of this div and don't care about
multiple inputs:
addElement: function () {
$("totalsContainer").update('<input type="hidden" id="finaltons"
value="' + totaltotal + '"></input>');
}
2. Create this hidden input in your form on server (in other words, input
should always exist), then just replace its value:
addElement: function () {
$("finaltons").setValue(totaltotal);
}
3. Combine both ways: check for existence of element (if not exists - then
create it), then update its value:
addElement: function () {
var input = $("finaltons");
if (!input) {
input = new Element({type: "hidden", id: "finaltons"});
$("formtons").insert(input);
}
input.setValue(totaltotal);
}
