can´t make it work

Hi , I was trying to make it work and can´t find the error.
I created the custom field named : CODE1
and pasted in the value field a mailchimp html code
when i use %CODE1% or %CODE1_RES% I see this as a text , not as a code embed.
Please see at http://www.viubeadministradors.com/evita-robos/
and the post editor here : https://www.dropbox.com/s/smebiuh5dgqteol/problem.png?dl=0

Even if a want to embed an url:
I created a a custom field named URL . The value: http://mailchi.mp/03012de9cdf6/que-no-te-roben-en-casa-durante-tus-vacaciones
write in the html post
%url%
and I see this http://www.viubeadministradors.com/1547-2/
can anyone help me?
Thanks!
