Foren / Cotonti / Skins / Quote Button

I'm trying to get a seperate Quote button below every post but I have a problem with the button still being displayed when a user is not logged in.

In forum.posts.tpl I have the following now:

<p>FORUMS_POSTS_ROW_TEXT}</p>
{FORUMS_POSTS_ROW_UPDATEDBY}
<div class="quote_button">
  {FORUMS_POSTS_ROW_QUOTE}
</div>

I tweaked the class "quote_button" to make it look like a button:

However when the user is not logged in, it's still showing a part of the button:

Is there a way to fix this so it's displaying nothing when a user is not logged in to post?
