How can i present 100% of one iframe within a containment block containing three iframes?

<HTML> <head> <title>Framset</title> <script src="../Javascript/mainframeY.js"></script> </head> <body bgcolor="#FFFFFF"> <IFRAME id="main" align="top" width="100%,*"... show more <HTML>

<script src="../Javascript/mainframeY.js"></scri...


<body bgcolor="#FFFFFF">

<IFRAME id="main" align="top" width="100%,*" height="30%,*" src="../Web Pages/navigation.html" scrolling="no" frameborder="0"></IFRAME>

<IFRAME id="main" name="Mainpage" width="100%,*" height="70%,*" align="middle" src="../Web Pages/Mainpage.html" frameborder="0" scrolling="no">

<IFRAME name="Footer" align="bottom" height="30%,*" width="100%,*" frameborder="0" src="../Web Pages/Footer.html" scrolling="no" ></IFRAME>
<script>document.getElementById('main'... = resizeIframe;</script>


Update: I would like to make it so that the web page in the middle iframe can be viewed in full without the need to have internal scroll bars. only the scroll bars on the web browser are needed.
