Simple stuff - using frames

This is a very simple question as I am a student trying my hand at a simple rails app. How do you use html frames inside the RoR scaffold. I can set the frame structure with no problem - but I am not sure how to point each frame to a .rhtml file.

I tried this code just playing around

<frameset rows="10%,50%">   <frame src="menu.rhtml">   <frameset cols="50%,50%">     <frame src="frame_b.htm">     <frame src="frame_c.htm">   </frameset> </frameset>

but I get the following error in each frame Routing Error

no route found to match "/menu.rhtml" with {:method=>:get}

I'm not sure how to set the routing obviously

Thanks to anyone who can help me
