i’m not exactly sure what your goal is (maybe a link?) but here’s some tips:
the link to the frameset on your nav should go to <a href=frameset.html target="_top">
if you want one of the frames in your directions frameset to contain the nav bar, just make it a blank page with just the nav bar in it, and don’t include the nav on other pages in the frameset.
to get out of the frameset, you want all links within the frameset that need to get out of the frameset to point to target=_top
also, and i don’t mean to flame, but web sites for businesses shouldn’t be made with FrontPage. It’s not exactly the professional standard. I won an award once for a Web site I made once for a magazine, and the guy who took over after me messed up the entire thing (and every single page of every issue before his) by using frontpage and whatever it does.
