Integrate .PHP page with wordpress blog thesis theme

I have a wordpress blog that uses the thesis theme: [login to view URL] I have created a php quiz and uploaded this to my blog/website here: [login to view URL] As you can see the [login to view URL] page does not have any theme or css styles as it is not a part of my blog and it is not a blog page or post. I want the [login to view URL] page to use the same theme as my wordpress blog so it blends in with the blog - so if I add a new category/page to my blog it shows up on my [login to view URL] page and has the same header, columns etc This page from the wordpress site called “Integrating WordPress with Your Website” was helpful:[login to view URL] However their suggestion did not work. An experienced wordpress programmer should get this working easily.
