A plea for help, with reps on offer to whoever can show me the error of my ways (blatant bribery I know, but hopefully it will work

)
Ive set up a fairly basic web site for my work, using only html code written in M$ Frontpage 2000 ('cos it came bundled with Small Business Server) and I don't know html or anything more sophisticated.. I know the style is a bit old, and the coding even worse, and do want to update eventually.
I have a small problem. The site is set up into frames, the top bar should be a constant navigation bar, with the side left frame, a local contents page and the right hand main area the main text. However I have links in the main text that should clear both the main right hand and left frames, and return to the home or index page. That sort of works, but I seem to keep the original top navigation bar, and then also load a new navigation bar duplicate under the original together with the main index page content.
With apologies for spamming (but I don't know how else to explain myself):
http://www.curchodandco.com/ is the index page. Now click on say "Building Surveying" and the "Party Wall Matters". That all works fine. Now scroll down the Party Wall text. At the bottom is a red logo. Click that should return to the home page, but instead does the duplicate reload
Any ideas?
