clark provided some of the answer, although you can do it without this. top.window.location.href="whatever url" should do what you want it is the same as <a href="whatever" target="_top" > should also do it. Because even in a three frame page, top should refer to the top most window thus the page holding the three frames when you change its location it should go to the appropriate url inputted. Try it if it doesn't work post it. I was trying to revert back to a page referenced by a particular frame.
