This is how I was intending the conditions to be used.... Let's say forumid 168 and 169 are for the New Advert Button and forumid 1 and 2 are for the New Ticket Button:

 <if condition="!in_array($foruminfo[forumid], array(168,169,1,2))">
      New Thread Button
    <else />
        <if condition="in_array($foruminfo[forumid], array(168,169))">
          New Advert Button
        <else />
          New Ticket Button
        </if> 
    </if>

As for the button code, you can basically copy the New Thread Button code and change the image source and link url.
