The coupon can’t cover all the cost? * Error: /v2/checkout/orders returned status 422 (Corr ID: f644523da7daf). * {“name”:”UNPROCESSABLE_ENTITY”,”details”:[{“field”:”/purchase_units/@reference_id ==’default’/amount/value”,”value”:”-9.5″,”issue”:”CANNOT_BE_ZERO_OR_NEGATIVE”,” description”:”Must be greater than zero.

See the example screenshot below that shows what I mean: [https://wp-express-checkout.com/wp-content/uploads/2022/02/apply-discount-spinning-wheel-example.gif](https://wp-express-checkout.com/wp-content/uploads/2022/02/apply-discount-spinning-wheel-example.gif) * Thread Starter [Fedep](https://wordpress.org/support/users/federicopalumbo/) * (@federicopalumbo) * [4 years, 3 months ago](https://wordpress.org/support/topic/problem-checkout-2/#post-15375186) * Yes i ask if possible to have the wheel also in the final button “place order” * Thread Starter [Fedep](https://wordpress.org/support/users/federicopalumbo/) * (@federicopalumbo) * [4 years, 1 month ago](https://wordpress.org/support/topic/problem-checkout-2/#post-15602352) * Hello please try to apply the spinning wheel to the “Place Order” button in the final Popup/Modal Window. Better would be to inhibit the button to avoid multiple clicking that (in my case) generated more purchases.
