Well, I added a new theme via my Yahoo (my Web hosting service) blog manager that uses WordPress. When I'm taken to the WordPress interface to make edits to the theme, it provides me a box with the code and links to all the files on the side. When I click on the CSS stylesheet link and make changes to that code, those changes appear on the page. However, when I click on the links to the other files and make changes, those aren't reflected on the page. I would assume if the CSS file is the correct one, all the other files in the same list should be as well.
I'm not sure how to send a link to the theme, since it's behind my password protected area.
