Adding Adsense with the Arthemia theme

Hey guys,

I just installed the Arthemia theme on my blog Kevin Pasco dot Com. It’s not very user friendly so I have to edit some code to get my Google Adsense ads to show up in the “advertisement” sections.

How would I do this? I found a blog that has the same theme and is successfully using Google Adsense in the advertisement box. Check it out here: http://rootparenting.org/

As you can see there is Google Adsense at the top and right side of the page. I talked to the owner and he said he edited the CSS code to do that but he didn’t tell me how.

How could I do that and what code would I use?

Thanks a ton in advance!
