Have you had a read through this --> http://www.manning.com/nielsen/SampleChapter5.pdf%5B/url%5D ? The sample chapter that I linked shows the "guru" method for performing what you want to do, along with lots of explanation.

If you have and are still encountering issues, then post what you have tried so far and I'll happily help. I'm unwilling to do all of the work for you, just as I'd be unwilling to do all of the work for anyone else that posts here but I'm more than happy to help.
