I have 2 frames in this site: http://www.69noites.com/

One is the site itself, the other is the "radio" frame.
I want that the hides the radio's frame, so i made it like this:

Code JavaScript:
<a href="JavaScript: top.joana.cols = "0,*";"><img src="close.jpg"></a>

The FrameSet code is this one:

Code HTML4Strict:
<frameset rows="92%,*" name="joana">
	<frame name="header" scrolling="auto" target="main" src="portal.php">
	<frame name="main" src="radio.php?r='.$radio.'" scrolling="no" target="main">
	<noframes>
	<body>
 
	<p>This page uses frames, but your browser doesn\'t support them.</p>
 
	</body>
	</noframes>
</frameset>


Can you help me?
