I am very new to Dreamweaver and Horizontal Spry Drop down Menu Bar and I am having trouble getting them to work. The browser displays the background gif for the menu items but I cant get the text to display. And the hover/drop down menu doesn't work. I have no idea how to fix this and I would be grateful for some help.

Here is my html code:
