you add it to the form, when you load the page for the first time, the input
line will be there, but as long as it's not been submitted there aren't any
$_REQUEST['updated'].

As I don't touch javascript, this will be updated each time you submit the new
values (no dragging of text sorry).
If you want to use javascript, then you need to write a code (javascript) that
updates the input fileds, but how you have to ask the javascript group.
If would do something like this, I think I would have selected to make a JAVA
applet. http://java.sun.com/docs/books/tutorial/uiswing/components/applet.html
