Well, take a look at your code, you are missing some very specific elements:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Untitled</title>
</head>
<body>
</body>
</html>
the document decleration type, the head and title tags. Also, very closely review your code, is there any open brackets that need to be closed?
Also, look at your frameset codes as shown below with errors noted:
<!doctype html public "-//w3c//dtd html 3.2//en">
<html>
<head>
<title>
Unofficial Drew Carey Fan Page</title>
<meta name="description" content="The site for Drew Carey Lovers">
<meta name="keyword" content="Drew Carey, TV, TV shows, comedy, sitcoms">

<frameset cols="100%" rows="100,*" border="1" frameborder="1" framespacing="1">
<frame name="top" src="
(Closing bracket before margins is a no no > <---- this could be causing your problem.) marginwidth="1" marginheight="3" scrolling="no" frameborder="no">
<frameset cols="170,*" border="1" frameborder="1" framespacing="1">
<frame name="left" src="

</frameset>
</frameset>
</HEAD>
</HTML>
IE is more friendly for the beginning designer and will allow you to make minor mistakes and still show your page, NS is not forgiving - it will not render your page unless your code is accurate.
Also, the only tags that are required in the frameset are the frameset tags, NO HTML tags (Head, title, html). You may keep your meta tags there.
Hope this helped!
