I have looked through the forum, and been looking at http://doc.silverstripe.com/doku.php?id=recipes:forms on how to make a form. But I am looking to put a form in the sidebar of the page.

This one seems unanswered: http://www.silverstripe.com/site-builders-forum/flat/89383?start=8 but seems the easiest method. Does anyone know how to get it working? Or what I should be looking to do?

So I have this form
http://doc.silverstripe.com/doku.php?id=recipes:forms
saved in <mysite>/code/RegistrationForm.php

and I am calling it in my sidebar with:

<% control Page(Subscribe) %>
inside Subscribe Page
$SubscribeForm
<% end_control %>

I have also tried making a subscription form in the usual way and calling the page into the sidebar.

Both don't seem to be working.

So I have this in my sidebar:

<% control Page(subscribe) %>
    $Subscribe
<% end_control %>

which is giving me: 0

Can anyone tell me how to get a form in the Sidebar?
