Redgirl:
If you don't know PHP, I suggest that you get familiar with how PHP works first. Not knowing PHP makes setting up the use of this and allmost any other appliction in PHP.
Please don't read my reply as anything else than a piece of advice. Learning PHP is not all that hard, but it takes a bit of reading and playing around. Please feel free to get help from anyone in the many different communities on the net :)
Wish you the best of luck - and that you get to make your site work the way you want!
