how do i get a different banner for different forums?

[patrickstar]

i want one banner in several forums and another banner in other forums. i used this to get the first banner working right:
<if condition="in_array($GLOBALS[forumid], array(28,29,6,5,19,14,21,13,3,15,10,16,22,7,18,17, 20,12))">BANNER</if>

then i used this one to try and get the second banner working but it didnt:
<if condition="in_array($GLOBALS[forumid], array(4,23,24,25,26))">
<a href=http://www.banner for site target="_blank"><img src="<A href="http://www.mysite/forums/gif"></a">http://www.mysite/forums/gif"></a>
</if>

i tried several variations of this: </elseif> with no luck.

can anyone tell me how to accomplish this? thanks.
