The tutorial says -
- Copy the bayside_beat folder into the Sites folder.The bayside_beat folder is the folder you will use as the root folder (main folder) for your Dreamweaver site. The content folder contains two rich text format (.rtf) files with text content for the web pages you'll build in this tutorial. The bayside_beat_comp.jpg image shows the design for the main page of the website (see Figure 2).
Did you add this bayside_beat folder as the root folder of the site in your site definition?
