This is not working with the latest woocommerce 2.4.8 update

@adstrakt still works fine https://dl.dropboxusercontent.com/s/7a4f1c72x58ejgy/2015-10-30%20at%2015.25.png?dl=0

any ideas of why it could not be working for me. The rest of snippets in functions.php are working fine. Just this one since i updated to woocomerce 2.4.8

One thing I do not like about this is that from the checkout page it won't display the error message until after the customer has entered all their billing, shipping, and payment information which could be very frustrating.

Perhaps it would be better to hook into the woocommerce_after_calculate_totals action which will display the message on the checkout page and not allow them to enter their information.
