java menu navigation issue

I have a java menu for my navigation on the site I am trying to develop - My first site really. . . .

The java used to feed the menu structure is nav.js
I have relative navigation paths in the file such as:

"home", /index.htm
"links", /link/index.htm
"travels". /travels/index.htm

This all works great from the main index page but once someone navigates to the links or travel pages (where I use the same menu), it won't reference back to the other pages. If I am in the travel page and click links menu, I get a file not found and it tries to go to URL .. . . . ../travels/links/index.htm

Do I have to have all naviation as a url? Will this make my get multiple counts on my counters?

Thanks for helping a newb.

use ..\ to go back e.g. when on the links page i.e. in the link directory and wanting to go to the index.html which is in the root directory you will be required to make a link for ../index.html
HOPE THIS HELPS
