the code shows the billing cycle in radio format but the price for the configurable option do not update in the order summary
https://prnt.sc/w8ri2w
in the above image the billing cycle is set to monthly for a dedicated server which has default RAM of 16 GB which I change to 32GB from the Ram configurable option and the price is +20 for the server, but this price did not updated in summary neither the price updated.
so that's why I though the code is from 2017 maybe it is no longer working the current stable release.
I checked this with other products also like for shared hosting, VPS and Dedicated server and this is the same for all configurable options. i,e if I buy an IP with the shared hosting, it doesn't add up in the summary neither the price adds up.
waiting for your kind reply
