Domain Help/Forwarding

Hello everyone,

I have a website hosted by Comcast and a separate domain name also hosted by Comcast. The domain is pointing to some website that I was building in the website creator that I somehow don't have access to anymore. How can I get the domain to point to the main website on the account?

Main hosted website: ProtoAnimation.comcastbiz.net

Domain: ProtoAnimation.com

Any help is appreciated.
