Issue With Conditionals

[Memphis834@yaho]

Hello,

I'm trying to display an html advertisement in one subforum. I understand that you can do this with conditionals.

<if condition="$forum[forumid] == 11">

html ad code here

</if>

I've searched a lot and all google search gives me is the same conditional list which is great but once it gets into questioning in regards to where you actually put that code, everyone seems to disappear.

Is the code above correct? The forum ID is 11. I have vbseo installed would that make a difference as far it being listed as 11 and not the actual name of the forum?

If the code above is correct, where do I place the code so that it appears in that one forum? What specific template do I edit?

I also have one other forum section I want to advertise in as well. Any help would be greatly appreciated!
