Hi, I was trying to use dTree navigation menu as follows:

d.add(4,0,'Profile','a href="page_1.html" target="content"');

Intention was, when i will click on profile (from my left sided menu) then the linked pages will appear on my right side frame named 'content'. But every time that is giving me the following error:

Firefox can't find the file at /C:/Users/Faisal/Desktop/friday/a href=.

How to use dTree menu with frame architecture?
