Wow - needless to say - this is more difficult then it seems. Searched around the internet - even wired up this

Code:
        $(document).ready(function() {
.
.
.
            $('.acs-input-field').live('keypress', keyPress);
        }
.
.
.
        function keyPress(event) {
            var wesThis = [];
        }

I might make it a function of the SAVE operation - since SAVE always refreshes all fields with a new GET from the DB.

As the javascript on the page is making up the JSON to send back to the web method that does the SAVE - I can switch up the case at that time.

oh well...
