DNS for a Blogger blog with a custom domain

I just bought a domain at DreamHost for a Blogger (blogspot) blog.

I finished steps (see screenshots below) but it didn’t work even I refreshed DNS.

Please check if I did something wrong. Thank you.

The domain hadn’t been successfully registered before its DNS was configured.

Case closed.
