Writing the results of JavaScript function to a table.

Question

Hi - I used the javascript from the post below to calculate a field based on two other fields. It works fine, but is only displaying it - not assigning it to the page item.
How can I assign the result to a page item so that it is processed with the auto DML when the page is submitted?
Thanks,
Matt
Re: How to multiply two textbox values and write it to another textbox?
function addthis(){
var val1 = parseInt($v('PX_VALUE1'));
var val2 = parseInt($v('PX_VALUE2'));
if ($v('PX_VALUE1') != "" && $v('PX_VALUE2') != ""){
var answer = val1+val2
$s('PX_VALUE3',answer);
}

Answer 1

What kind of item is PX_VALUE3 - a text item or a display item or something else?
What happens if you manualy change the value of PX_VALUE3 to something? Does the DML Process save that value or not?
What is the source used and source type of your PX_VALUE3 item - is it only when... or always... / is it a database column or static assignment?
