Need Help Debugging Script/Error in Script - Error using Frames and HTML

I am working with some existing Java code that uses frames to format the web page. There also are javascript pages which display HTML. Independently they both work great. Now they want one of the javascript pages to be set up such that on a click in the top frame, one of the javascript pages displays. I added the code together and it looks good, but when I click on the link to display the javascript page,the page is displayed inside one of the frames and behind the existing information.

What is the basic problem? I want the page with the frames to go away entirely and show the javascript page that is working correctly now.

Not sure of the basic problem -- is it the frameset or the link?
Thanks!

I have ben searching around on the web and found z-order. That might make the screen appear OK, but I am concerned about all the other pages the user can go to after.

What I really need to do is REMOVE the Frameset and bring up a Java or Java Script page that displays the non frames HTML pages that already exist.

If I do not REMOVE the frameset, then everything I have tried simply puts the HTML inside a piece of the frameset.

I really do not work in this space. So I am probably explaining it poorly, but any help or clues to what I am doing wrong would really be appreciated!!!

Thanks.

It would be most helpful to see at least some "bare bones" code to get a better idea of what's going on.
