issues creating dns zone in plesk

[Tandrinium4]

I tryied to ccreate the zones, but if I add you server names to CNAME register I get an error from plesk.

In, in other way, I try to setup the Cname as

af.domain.org and value as af.domain.org I get an error telling that af.domain.org doen't resolve to anywhere.

I'm a newbie in plesk.

Could you help me?
Thank you in advance

Hi,
If you can send me access info I can create cname records for you.
