Trying to find 2 "$navbits" Variables

[TrinityEnt]

Im trying to do a tab system

<li<if condition="("$navbits[lastelement]" == "Section Title")">
 class="current"</if>
<if condition="("$navbits[breadcrumb]" == "Section Title")">
 class="current"</if>>
<a href="#" title="Tab Title"><span>Tab text</span></a>
</li>

I know you guys get threads about tabs all the time, but none of the modifications offered match what i want.
I want the tab to stay highlighted as long as a person is in the section.
Sort of like vbulletin.org`s.
