Google Adsense - weird choices

[TimberFloorAu]

Posted this on vb.com ( no real replies yet ) so will bug you guys

I really am not getting this Google Adsense advertising hook for VB 4.

Perhaps someone can explain.

Please see attached image to understand

We have 3 choices:

1 no ads
2 low advertising
3 high advertising.

My issue is HOW do we make it so that advertising is displayed based on usergroup conditionals.

I have added respective code to the adverts: such as- wrapping the ads in condition

<vb:if condition="is_member_of($bbuserinfo, 1,2,3)">
advert
</vb:if>

which yeah in theory works, but the ad manager, bypasses all of this by inserting adverts into header and footer as a routine.

Whats the go there, how the hell do we control the :- adverts in Header and Footer , either way they ARE added with no conditional control

No Google AdSense Ads
Low - one small text-only advertising unit under the navbar and one small unit in the footer
High - one medium advertisting unit under the navbar, one unit before the footer, and one unit for guests in the first post of a thread

Am i missing something painfully obvious, have we got a corrupt manager, or has someone overlooked the fact there seems to be a choice missing ?
