A little Javascript will do the trick. It will be easy if you use something like jQuery to help you out. Just bind each field in your form to the change event using the change() method, and then update the "cascaded" field to the value passed to the change() method.

For example, consider the HTML:

<form>
  <input type="text" id="field1" />
  <input type="submit" />
</form>

And supposed you want to update the following div dynamically as the above form is edited:

<div id="field1_val"></div>

Add the following script to the head of your HTML:

//This will just make sure you're using the awesomeness of jQuery...
<script src="http://code.jquery.com/jquery-latest.js"></script>

//This will bind your field to the change event using jQuery
<script type="text/javascript">
  $("#field1").change( function() {
    $("#field1_val").text($(this).val());
  });
</script>

Hope that points you in the right direction.
