script upgrade - whats wrong?

[Rich]

Hello,

I am trying to upgrade some calls so that this will function properly:

 
<if condition="$show['guest']"> 
<!-- guest welcome message --> 
<br />
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<thead>
<tr> 
<td class="alt1" colspan="6">
     <phrase 1="faq.php?$session[sessionurl]" 2="register.php?$session[sessionurl]">$vbphrase[first_visit_message]</phrase>
     $vbphrase[welcome_ads]
</td>
</tr>
</thead>
</table>
<!-- / guest welcome message -->
<else /> 
<if condition="!is_member_of($bbuserinfo, 3)">
<!-- / unconfirmed user message -->
<br />
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<thead>
<tr> 
<td class="alt1" colspan="6">
   $vbphrase[welcome_unconfirmed]
   $vbphrase[welcome_ads]
</td>
</tr> 
</thead>
</table>
<!-- / unconfirmed user message -->
<else />
<if condition="$bbuserinfo[posts]<1">
<!-- never posted message -->
<br />
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<thead>
<tr>
   <td class="alt1" colspan="6">
     <phrase 1="$bbuserinfo[username]">$vbphrase[welcome_neverposted]</phrase>
       $vbphrase[welcome_ads]
</td>
</tr>
</thead>
</table> 
<!-- / never posted message -->
<else /> 
<if condition="$headerstime - 1209600 > $bbuserinfo[lastpost]">
<!-- never posted message -->
<br /> 
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center"> 
<thead>
<tr> 
     <td class="alt1" colspan="6">
       <phrase 1="$bbuserinfo[username]">$vbphrase[welcome_postmoreoften]</phrase>
         $vbphrase[welcome_ads]
   </td>
</tr>
</thead>
</table>
<!-- / never posted message -->
</if>
</if>
</if>
</if>

When I added it to my header, the guest message showed up like it should. Once i registered, I recieved my "you haven't posted message before I was confirmed. Then on page refresh, I got the unconfirmed message and even after confirmation, it remained. What's wrong with the code? I can't figure it out. lol

This was originally written for 3.0.X. (don't recall the author.) I have been attempting to upgrade it to work with my 3.5 board.
