Code Question

[Mum]

What is wrong with this bit of code? I am trying to place it under the sig. But for some reason it's not working, and all the id numbers are correct, i've checked them a million times LOL

<if condition="in_array($post[membergroupids],array(82))">
<div class="vBadvertisement">Signature Sponsor
<br /><a href="$post[field24]">$post[field25]</a>
<br />$post[field26]
<br /><br />
<a href="/payments.php">Get a sig like this!</a>
</div>
</if>
