I'm a little confused. Where am I supposed to insert the "panel" string? I replaced the three "image" lines with the panel part, but it doesn't seem to be functioning properly. What else do I need to edit, and where do I edit it, and how? (Sorry if my questions are a little stupid, I'm very confused with the whole 'Template Copying' and 'Template Editing' part.)

Also, the 3rd and 4th example on the Test Wiki are exactly what I want. Is there a way to change the name of the tabs too?
