Hello,
Can you please explain your issue ? The element which is not working ?
Right now, I got the impression that you need help to configure prices on variants, which will be an HikaShop support question and is not related to HikaSerial.
If you have issue with the coupon price in HikaSerial ; please provide details about your current configuration so we can understand it and help you to improve your settings.
Regards,

By the way, do not send me private message, use the "contact us" form instead.
