While using NAMESERVERS are the preferred method of pointing to your hosting account, not all means of DNS need to use them. Especially if you want to host the site here, the emails elsewhere, etc. In order to show your website here, you will need to direct your domain here somehow. To do that you will need the following records on your domain to work.
www IN CNAME 14400 domain.com
domain.com IN A 14400 xxx.xxx.xxx.xxx
To get that A record, you just need the IP from your cPanel located on the right under Server Information. Not all IP's are the same and cPanels can have a different IP.

Once you set those records, the domain will load here and all other services will be hosted elsewhere.
