Works perfect! Thanks for the help!
Product is showing in the cart but I also get an error message: Notice: Undefined index: line_total in /home/americ51/public_html/wp-includes/class-wp-list-util.php on line 157

1) Add qty 1 to cart
2) View cart
3) Manually apply coupon code “10KIG”
Response message from WooCommerce is “Coupon code applied successfully”
