Simple Search Bar?

[Greeksgal]

I'd like to place a simple search bar at the top centre of one of my forums but not on my front page (i.e navbar or header) actually in one of the forums under the catagories. I've tried the code below which works but it allows search to search the entire forum, I only want it to search the forum it's placed in...any ideas?

<if condition="$forumid == 25">
<!-- Search Box -->
<td valign="center" class="alt1"> <div style="white-space:nowrap">
<form action="http://www.**************.com/search.php" method="post">
<input type="hidden" name="s" value="" />
<input type="hidden" name="do" value="process" />
<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />
<input type="hidden" name="showposts" value="0" />
<input type="hidden" name="quicksearch" value="1" />
<input type="text" style="width:100px;" class="bginput" name="query"/>
<input style="font: bold 10px Arial" type="submit" class="button" value="Search" /></form> </if>
<a style="text-decoration:none" href="search.php" accesskey="4" rel="nofollow" id="navbar_search"

class=""></a>&nbsp;
</div></td>
<!-- /Search Box -->
