Question about Conditionals

[baze22]

I'm trying to get adsense integrated into my forum. I only want the ads showing in showthread displays and forumdisplays and I want to exclude certain (non-public) forums. I've used the following:

<if condition="THIS_SCRIPT == 'showthread' || THIS_SCRIPT == 'forumdisplay'">
<if condition="(f <> 6) && (f <> 7)">
ad here
</if>
</if>

It restricts it to the page but still shows for all forums. I'm not sure of the right variable name to use for the forumid (I have tried forumid). Is there a list somewhere listing variables available to use in the conditional statements.

thanks,

basil
