Redirecting www to a subdomain

Hi there, i have a domain name issue

My site (hosted by Photodeck) is working perfectly : paysages.arly-photography.com

I want arly-photography.com and www.arly-photography.com to redirect to the site as well (visible redirect)

I've tried many times to add a redirection, but it doesn't work...

Attached is my DNS zone, what am ia doing wrong ?!
