values no showing ??

[chewy]

Whats wrong with this code, im trying to add it to a side bar on my forum home but none of the stats show but the $vbphrase's are.

PHP Code:

<tr>
    <td class="$bgclass">
        <span class="smallfont">$vbphrase[members]: $numbermembers<br />
        $vbphrase[threads]: $totalthreads<br />
        $vbphrase[posts]: $totalposts<br />
        $vbphrase[top_poster]: <a href="$vboptions[bburl]/member.php?$session[sessionurl]u=$topposter[userid]">$topposter[username]</a> ($topposter[posts])<br /></span>
    </td>
</tr>
<tr>
    <td class="$altbgclass"><span class="smallfont"><phrase 1="$vboptions[bburl]/member.php?$session[sessionurl]u=$newuserid" 2="$newusername">$vbphrase[welcome_to_our_newest_member_x]</phrase></span></td>
</tr>
