Hi,
Would it be possible to have more details about the product and about your HikaMarket configuration ?
Does the product have characteristics ? Does the product already have variants ?
Your website have a account restriction so we can't see the product page you linked.

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