Okay, it "sounds like" you have one website and it is at yourname.squarespace.com and you purchased a domain name to point to it. A domain name that just points to another domain can only go to that one page, not any other pages. Such a domain structure is a vanity domain. That is, it gives the impression of being the true domain but it is not. Also, search engines will not index domain pointers. Some hosts, such as wordpress.com, will work with you if you buy a domain name through them and will make it work the way you want. You might contact people at squarespace to see if they support letting personal domains be the true site name. If not, your only real solution is to move your web content from squarespace and have it hosted on a normal web host account. Then your domain name will work exactly as desired.

your questions is confusing u wanna redirect?

i have a domain with Domain.com and a site with squarespace.

So i linked the 2 sites but now itll only show my domain (mydomain).com no matter whcih page im on.

like if i go to one of my articles itll say (mydomain).com instead of (mydomain).com/articles

Ive tried recreting the CNAME and pointer but it still doesnt work. any help?
