Ads won't show to registered users...

I checked the template and this is what it has. I set up the ads using the wizard under advertising.

First Post Content -

<div id="ad_thread_first_post_content"><div id="snack_dex3"></div><vb:if condition="$adsshown[] = 1"></vb:if></div>

Last Post Content -

<div id="ad_thread_last_post_content"><div id="snack_dmpu"></div><vb:if condition="$adsshown[] = 3"></vb:if></div>
