Turn off 1st post adwords ad for just 1 style

[rfsforums]

I have adwords ads turned on in first post for unregistered users and I'd like to edit 1 style so that it does not display the first post ad regardless of who's viewing it. I've tried editing the postbit for that style but either I'm just not removing that rigt section of code or I'm in the wrong area.

any ideas?

Thanks!
