Home Woocommerce cart modifications being overwritten by checkout.js
 I'm hooking into Woocommerce's woocommerce_calculate_totals to set a minimum order amount for age verification. Basically the customer needs to have an order minimum of $1. This works on the view cart page, but the subtotal is getting overwritten by checkout.js - I can see it being modified after page load. Here's my code in functions.php: function hv_set_min_total() { if( is_checkout() ) { global$woocommerce; // set minimum cart total $min_cart_total = 1; // Total used before taxes and shipping$total = $woocommerce->cart->subtotal; // compare values if($total < $min_cart_total ) {$diff = $min_cart_total -$total; $woocommerce->cart->subtotal +=$diff; $woocommerce->cart->cart_contents_total +=$diff; $woocommerce->cart->subtotal_ex_tax +=$diff; } } } add_action( 'woocommerce_calculate_totals', 'hv_set_min_total' );  I've also tried hooking into various other hooks that all change the subtotal, but still get overwritten by the checkout.js file. Any ideas on how I can stop this from happening? Other things I've tried, but still get removed: Add Fee Negative discount
