I deleted the breadcrumbs box from the original pages and want to put them back

I deleted the breadcrumbs box, and tried to put it back, and now cannot get it to work when I put it back in.

How to I set up the breadcrumbs?
Also, will the breadcrumbs work in the header?

Is this an automatic feature, or do I have to build each text box on each page and post?

Will the Breadcrumb NavXT plugin work with UpFront/Spirit?
