The problem is: how can I validate add up of both 3rd Party Transfer and Bill Payment can not exceed 10,000?

you wouldn't be able to javascript to get the values from the previous page. any reason why you can't access them from the session to compute? remember that if you want to use javascript to calculate the totals, you'll need to render the other value(s) on the page (you could use a hidden input so it doesn't show up).
