Creating new subdomain

Hi Mike, thanks for your reply.

I followed your directions and received the error that “skiminar” already exists. I found in HubSpot a page telling me there are DNS errors (see screenshot). But at the top left it says “Connect a primary domain.” So I’m a bit confused:

Do I need to register a subdomain with my domain provider?

Does this page (screenshot) say I’m trying to create a subdomain, or did we do something wrong originally and are in the process of doing something other than creating a subdomain?

Thank you so much for your help!
