OK, I think I get what your trying to say. Your saying that there are two links within the html page named index.htm? If you want to link a hyperlink to another html page that pressumly would load the external article, this is what would the coding be:
<iframe name="cwindow" width=670 height=290 frameborder="no" scrolling="no" src="root.htm"></iframe>
That above defines the iframe window. Below is the attached coding to a hyperlink:
<a href="root.htm" target="cwindow">Home</a>
Does this help?
