Style/Positioning banner adverts

Hello All. I think this plugin is great, just what I needed – perfect in fact.

However, I’m having some issues with the positioning of the adverts in the header – I assume I need to insert some more code but I’m a bit lost as to what to do next. The banners need to appear to the right of the header, not under the blog logo.

Any help appreciated.
