modify this code for admin group

[MultiSync77F]

How do I change this to search for usergroups?

I found this code in my postbit template. I'm assuming its the code I need to use.

How do I modify this code to change the color of the text if the user is of the admin group? I have disabled colors BBCode and have a black skin. I want admins to have a blue type font but all other usergroups just use the normal font.

PHP Code:

<!-- message -->
<div id="post_message_$post[postid]">
$ad_location[ad_showthread_firstpost_start]
if usergroup = admin <font color="#2d8fc4"><b>
$post[message]</font></b>

if usergroup not = admin $post[message]
</div>
<!-- / message --> 


I don't know the PHP syntax

thanks
