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. https://premium.wpmudev.org/forums/topic/domain-mapping-for-dummies#post-124788

I have http://www.youthministryresources.com and I want to practice the set-up with domain mapping, so I set up the site http://catholic.youthministryresources.com.

Now I have the domain http://www.catholicyouthministryresources.com that I would like to use in place of http://catholic.youthministryresources.com.

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

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