Problems about frames

Hello, I have made a website called gamerbox.tk and I have two frames on the first page, the top and main frames there working well but I have found out something, which is that if you go to another page and click homepage it will take you to the INDEX PAGE ading on another frame, so does anyone know if there is a way so the the frame knows when to add on a frame and not so if your going to the homepage for a secound time it will not add on another top frame.

P.S: I know if I go to the other pages and change it so it takes you to the homepage.html instead of index.html but the reason why that im not doing that is beause I need to get better at code and as well im not going to change the page link on all 192 pages!

P.S.S: Here is a diagram of what it looks like when you go on it for the secound time
