Little help with If condition

[qpurser]

I am not that great with PHP coding and struggled with it for hours now but can't get it work.

I have a plugin that created a variable for a Category in my classifieds plugin:$catid
I want to show some text depending if the user is a member or not but only in a particular Category

What I am trying to do
If somebody looks up an item in
Category 3 and he is a member (usergroup= 9) it should say "Buy this item"
Category 3 and he is not a member (any usergroup besides 9) it should say "Members ONLY sale"

Any other category and no matter member or not it should say "Buy this item"

I tried this but didn't work

<vb:if condition="$catid == 3">
<vb:if condition="$vbulletin->userinfo[usergroupid] == 9">
<font color="#FFFFFF"><b></a>Buy this item</b></font>
<vb:if condition="$vbulletin->userinfo[usergroupid] <> 9">
<font color="#FFFF00"><b></a>Member ONLY sale</b></font>
</vb:if>
</vb:if>
</vb:if>

<vb:if condition="$catid <> 3">
<font color="#FFFFFF"><b></a>Buy this item</b></font>
</vb:if>


What am I doing wrong?
Thanks for any help

Instead of:

<vb:if condition="$vbulletin->userinfo[usergroupid] == 9">

use:

<vb:if condition="is_member_of($bbuserinfo, 9)">

And, you'll need to make sure $catid is preregistered for use in that template. Cellarius wrote a really good article that you may be interested in to help with that - [vB4] Rendering templates and registering variables - a short guide

The best place to post for more help with modifying your site is over on vbulletin.org, the modification site.
