Help with Code

[Mum]

I am trying to achieve something, that i know is possible, but i am unsure how to do it.

I have a special sponsors group. They are allowed to add a link/title and text to their sig. However, i dont' really want it using up their signature space, so i was trying to do this.

I added in user profile fields for link/title/text and now i'm trying to put this in the postbit - but i cna't get it working. Can someone help please?

<if condition="in_array($post[membergroupids],array(82))">
<div class="vBadvertisement">Signature Sponsor
<br /><a href="$post[field24]">$post[field25]</a>
<br />$post[field26]
</div>
</if>

Just to clarify - i want this ad to show to everyone on the site, but i only want it to show if the poster is in the sponsor group.
