Domain Mapping for a Dummy

This is a continuation of a previous post that was not in the support section that ended being a support topic.

I have and I want to practice the set-up with domain mapping, so I set up the site

Now I have the domain that I would like to use in place of

I have both domains parked on the same cpanel and am attaching the screenshot of DNS settings for the domain. What else do I need to do?

I have a Dedi IP and latest versions of WP and Domain Mapping.
