$totalonline, $numbervisible, $numberguests in navbar?

[slobra]

I added the code in red to my navbar template:

<strong><phrase 1="$bbuserinfo[username]" 2="member.php?$session[sessionurl]u=$bbuserinfo[userid]">$vbphrase[welcome_x_link_y]</phrase></strong><br />

$vbphrase[currently_active_users]: $totalonline (<phrase 1="$numbervisible" 2="$numberguests">$vbphrase[x_members_and_y_guests]</phrase>)<br />

But when I view the page, it shows up as follows: Online Users: 217 ( members and guests) - notice it's not getting the values for members and guests. What else do I need to add to display those values? Thanks for the help guys.
