Unable to use forum conditional in header or threadbit

[LifesGreatestGift]

I want to use the following conditional

<vb:if condition="$forum[forumid] != x"></vb:if>

to disable the viewing of notices in a specific forum so I open up template "navbar" and add it around the notices code and it does not work. Any ideas?

<vb:if condition="$forum[forumid] != 159">

<vb:if condition="$show['notices']">
<form action="profile.php?do=dismissnotice" method="post" id="notices" class="notices">
<input type="hidden" name="do" value="dismissnotice" />
<input type="hidden" name="s" value="{vb:raw session.sessionurl}" />
<input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />
<input type="hidden" id="dismiss_notice_hidden" name="dismiss_noticeid" value="" />
<input type="hidden" name="url" value="{vb:raw return_link}" />
<ol>
{vb:raw notices}
</ol>
</form>
</vb:if>

</vb:if>

[ForumsMods]

For forums:
<vb:if condition="$foruminfo['forumid'] != '159'">
</vb:if>
For Threads:
<vb:if condition="$threadinfo['forumid'] != '159'">
</vb:if>
