Removing banner ads

[Ninth Dimension]

Hi, i'm not sure if this is the right forum or not (if not, sorry) but I was wondering if someone could help me out with a very minor mod.

I've added some banners to my forums, and am in the process of setting up a paid subbscription for any members that want to browse banner-free. I've set-up their special usergroup (Friends of Arathor), changed the permissions for the group (such as giving them extra PM space, larger avatars, custom titles, etc..), but now I need to set it so they'll no longer see the banners.

I was going to use one of the groovy template based <if> commands, but truth is, I don't fully understand how they work... What I want to do is say:

if usergroup != X or Y, show banner.

X and Y being the admin and friends usergrounds.

Can someone let me know the exact code please? Thank you.

UPDATE

OK, I've worked out half of it:

<if condition="$bbuserinfo[usergroupid]!=6">

<!--banner code-->

</if>

But I need to put two usergroups in there, not just one - any ideas?

UPDATE 2

OK, I've done a bit more work, and think that this should work:

<if condition="$bbuserinfo[usergroupid]==10">
<!-- nothing -->
<elseif condition="$bbuserinfo[usergroupid]==6">
<!-- nothing -->
<else />
<!-- banner -->
</if>

But it doesn't.. anyone?

UPDATE 3

OK, I'vee fixed the problem, but not quite in the way I wanted to.. oh well, it's done now, and it works.. here is what I did:

'phpinclude_start' template:

PHP Code:

// check for friends of arathor or admin usergroup
if (($bbuserinfo[usergroupid] == 6) OR ($bbuserinfo[usergroupid] == 10)) {
    $friendsofarathor = true;
} 


'header' template:

<if condition="$friendsofarathor">

<!-- nothing -->

<else />

<!-- banner -->

</if>

As you can see, this works, and in the longrun might benefit be further (I'll be able to use the $friendsofarathor variable all over the place), but I'm still keen on working out how to do it all in one, without having to edit the phpinclude_start template, so if you know, please do tell
