.com.com extension?

How is that I am getting a duplicate title error at this url?  How would I even fix that?

I will admit that the URL itself is a little weird but if you are pulling this from a tool in SEOMoz it will tell you what other pages have the same title as your homepage.  Not sure why this is picked up but your title tag is <title></span><span>Andie Mueller Web Works | Wordpress Support | SEO</title> so I would just verify other pages are not using this and if you cannot find it, well I wouldn't worry too much.
