Thank you for your help with the CB Action Field issue, that case is solved. I do not know how to mark that topic as solved.
Now I'm on the 2nd face, which is the time release articles in the classroom page.
I've created 2 new fields, just like the Time Release document indicates
1. Subscription Date Field
2. Days Since Subscription
I've created a Category, called "Classroom", in which I have the articles to be time released once a week.
<p>[cb:if cb_daysdiffquery>="0"]</p> (different articles with different Time release 0, 8, 16, 31, etc)

</br>
<p>[/cb:if]</p>
When I make a new subscription on the Edit Profile the Subscription date shows up empty and can be modified to set whatever date I want, which is good for testing the system, and it works fine.
The problem is that when I make a new subscription in the system the articles that are set to "0" do not show up, because at the time of Subscription date field shows empty.
How can I make it active?
So when the subscriber signs up that field is populated and the system starts to count the days automatically.
Thanks,
