Redirect in Java script not working

We have a simple frame based website.  http://www.onlinetechhelp.com/  When you enter you need to check a box saying you agree to the disclaimer. This sets the cookie so you don't have to do this the next time.  You will jump straight to the home page http://www.onlinetechhelp.com/support/home.htm  The problem is that initially it goes to http://www.onlinetechhelp.com/home.htm which is wrong.  If you close and re-enter it finds the correct path.  I don't speak Java and but I want to find the right line to redirect it to the right path the first time.  The script below is from the file called disclaimer.htm  near to the bottom there is a "redirect" statement but that has no effect.  I feel like I am overlooking something simple.  Help!
