no question is a bad question!

As we started to create our stylesheets and actually get some forms to display on the web, we had some trouble getting all of our text boxes to allow type for text.  I believe this is because we made those boxes to be uniquely generated from the database ( like the primary key customer_id).  Anyways, i guess my question is what exactly are the files we need in the same directory?  We have most of our files in the same directory but I just wanted to make sure so that we can remove that situation as a possible problem.
