Add another domain to deluxe hosting plan

Hi, Im hosting a website at godaddy.com. I upgraded to deluxe hosting as I wanted to add another domain with DIFFERENT content to the hosting space. Somehow I cannot make this work - my first domain is populating the root of the directory, maybe this is it. I want to pay somebody to do the following: 1) leave the "primary domain" with the current content 2) Upload wordpress to the new domain - still on the same hosting space. Ill attach a screenshot of the server as of now - again, the fact that the forum is on the root may have something to do with it....?
