If you want to replace the level above the frame, TARGET="_parent", to replace the lot TARGET="_top"

Another problem you can find with multiframe layouts, is that wiythout resorting to (potentially disabled) javascript, you can only refrest one frame as a link - unless you split the frameset into two levels.

Eg. Level 1, is a top and rest frameset named navbar and navbody.
Level 2, another frameset page (more than one of them) can load a left and right frame in the navbody area - you can still reference the frames individually, and you can also replace the entire navbody by loading a different frameset - it's a powerful trick, but you really need a clear picture of how you want to organize the frames.
