A simple I-frame setup...
<iframe name=i_frame src=somepage.html width=300 height=300 border=1 frameborder=1
scrolling=auto></iframe>
The i frame name can be anything as long as it ends with _frame.
Scrolling can be set to no, yes, or auto.
Source is the page that you want to originally appear in the i-frame.
If you have links that you want to click then have them appear in the i-frame,
you would use <a href=somepage.html target=i_frame>Link Name</a>.
The target name has to match the name of the i frame.
Hope it helps.
