I'm not a programmer, but I can find my way around wordpress pretty well and some php. I found a script/program for making a classifieds page, so I uploaded it and setup my database and its working fine. you can see it here. its located in a subfolder where as my wordpress install is in the main directory.

http://portfoliosfriend.com/jobs/

so, rather than have this running on its own page, I would really love if somehow I can call the index.php file into my wordpress content area. now I have no clue it this is possible to do with php, but I hope it is. I can then edit the css for the classifieds so it fits in my content width. or, if there is another way of doing this, I'd love to know. initially I had the idea of making a new page in wordpress, and then typing the necessary code in that page which will call my other index.php to load. again, not sure if that is possible. any help will be great! thanks

have you tried just including the jobs/index.php file into your wordpress/index.php file? I would first make a copy of the file stripping out the header/footer html of the page and including that file into the wordpress/index.php file where you want them to show up.

if you want to wrap each job item as you pull it up with your wordpress theme, you can use Page Templates to do so which would act as the "viewitem.php" page.
