About This Solution

Are you writing a custom snippet which makes changes to the order totals based on the billing county / state?

Perhaps your snippet adds a fee to the order depending on the billing state / county but the totals are not refreshed in the “Your order” section of the checkout.

This snippet will update the checkout totals when the billing state / county is selected on the checkout.
