Hello, I just started coding today and I figured the best way to learn would be to follow a tutorial and build a website. Well, I did that (minus uploading the website) and now I am trying to do some additional stuff.

My problem is this...

I have created a main page divided into two frames (columns). In the first frame I have a list of links (or soon will) and in the second frame I have related material. My goal is to be able to click one of the links in the first frame and have it open in the second frame. I do not know how to do this. At the moment it only changes the first frame.

Here is the related code.
The Main Page
Code:
<html>
<head>
<title>The Main Page</title>
</head>
<frameset cols=170,*>
<frame src="sitenav.html">
<frame src="CubePage.html">
</frameset>
</html>
First Frame
Code:
<html>
<head>
<title>Site Navigaton</title>
</head>
<body bgcolor="ccffff">
<h1><u>Navigate</u></h1>
<a href="CubePage.html">My Cube!</a> <br />
<a href="links.html">Links</a>
</body>
</html>
Any help is much appreciated, thank you.
