You have to change your domain nameservers to ours temporary, then add your domain though Addon domains section in cpanel, after this create your subdomain in subdomains section, then change your nameservers back to blogger ones (or the nameservers of your domain provider).
Step 2
follow this article
Create a Cname record named example (can be replaced based on the name of your subdomain, enter example if it is example.domain.com) with value your main domain (can be find in cpanel->account details), then wait for up to 24 hours.
You need to set up that record with Namecheap. That’s how you can use Namecheap’s nameservers for your domain and direct people to your account here.
As for how to set that up with Namecheap, I don’t know exactly. Maybe their support can help you.
But in general, there should be some kind of system for “DNS Records” where you can add new records. It should be of “type: CNAME”, with “host: kid” and the target being your hosting accounts Main Domain. The exact name of the fields varies by provider.
The Main Domain can be found in your client area and the control panel. Make sure to look specifically for something called the “main domain”.
