Help with $navbits[lastelement] and $navbits

[ForumsMods]

I need put $navbits[lastelement] and $navbits in header, How i can do it??

[Dismounted]

The header template is already evaluated before $navbits is initialised.

And there is any way that It can do?
I found this code:

// #############################################################################
/**
* Returns the HTML for the navigation breadcrumb in the navbar
*
* This function will also set the GLOBAL $pagetitle to equal whatever is the last item in the navbits
*
* @param    array    Array of link => title pairs from which to build the link chain
*
* @return    string
*/
function construct_navbits($nav_array)
{
    global $pagetitle, $stylevar, $vbulletin, $vbphrase, $show;

    $code = array(
        'breadcrumb' => '',
        'lastelement' => ''
    );

    $lastelement = sizeof($nav_array);
    $counter = 0;

    if (is_array($nav_array))
    {
        foreach($nav_array AS $nav_url => $nav_title)
        {
            $pagetitle = $nav_title;

            $elementtype = (++$counter == $lastelement) ? 'lastelement' : 'breadcrumb';
            $show['breadcrumb'] = ($elementtype == 'breadcrumb');

            if (empty($nav_title))
            {
                continue;
            }

            $skip_nav_entry = false;
            ($hook = vBulletinHook::fetch_hook('navbits')) ? eval($hook) : false;
            if ($skip_nav_entry)
            {
                continue;
            }

            eval('$code["$elementtype"] .= "' . fetch_template('navbar_link') . '";');
        }
    }

    ($hook = vBulletinHook::fetch_hook('navbits_complete')) ? eval($hook) : false;

    return $code;
}

I think it may be useful

That function is used to compile the navbits from an array of breadcrumb elements - this array does not exist, or is not complete, when the header is evaluated.
