Apply mod for certain forums

[lttcoder]

Hi!

look at this attachment

the hack : https://vborg.vbsupport.ru/showthread.php?t=95663


The problem with this hack is that it will be displayed for ALL THREADS.
But what I want it to do is display for threads inside certain forums.

Lets say I have 4 forums:
PC GAME discussion
PS2 discussion
XBOX discussion
Game releases

And the header should only appear inside GAME RELEASES.

This is the code for the header information.
Any change that should be done here?
Like :
if current.forum = forumid,forumid2,forumdi3 then display header?
<table align="center" border="0" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" class="tborder" width="100%">
<tr>

<td class="tcat"><span class="smallfont"><b><center>Thread Informations</center></b></span></td></tr>

<tr valign="middle"><td class="alt1">
<br />
<center><h3>$thread[title]</h3>
<h4>$vbphrase[views] : $thread[views]</h2>
<b>$vbphrase[replies] : $thread[replycount]</b><br /><br />
<b>Users Viewing This Thread : $activeusers</b></center>
</td>
</tr>
</table>
