Well after doing alot of searches on some different forums, I found a bit of a modification for what I needed to do, so I figured I would share with people in case they are looking to do the same thing.
I just added a few "or" commands I guess they would be called and it works great now. This is what I did.
Code:
<if condition="is_member_of($post,6)or is_member_of($post,24)or is_member_of($post,25)or is_member_of($post,26)"><div class="adminclass">$post[message]</div>
