Hi, i'm working on my collage's professor's request. I'm trying to create frame based web pages.

I need this layout



But I cant create the center bottom.

There is the code:

Code:
<frameset rows="12%,*">
<frame name="ust" src="ust.html">
<frameset cols="14%,*,14%">
<frame name="sol" src="sol.html">
<frame name="ortaust" src="orta-ust.html"><br/>
<frame name="ortalt" src="orta-alt.html"><br/><br/>
<frame name="ortal54t" src="orta-alt.html"><br/>
<frame name="sag" src="sag.html"><br/>
</frameset>
</frameset>
