Show icons for specific usergroup (threadstarter) in threadbit?

[MarkFL]

On my local dev site (vB 4.2.x) when I edit the threadbit template, in the status icon block section to read:

			<!--  status icon block -->
			<vb:if condition="is_member_of($thread, array(6))">
			<a class="threadstatus" rel="vB::AJAX" <vb:if condition="$show['threadcount']">title="{vb:rawphrase have_x_posts_in_thread_last_y, {vb:raw thread.dot_count}, {vb:raw thread.dot_lastpost}}"</vb:if>></a>
			</vb:if>

Then in the forum display, I see the following:



The user "Randall Flagg is not a member of usergroup 6, while "MarkFL" is.
