Have A Layer Appear Over A Frameset?

[SlickVic78]

Hello my fellow Web Gurus,

I am messing around with layers and was wondering if it is possible to have 1 layer appear over a frameset.

Here is the example:

Picture this - a popup window with a frameset within (splitting the window into 2 sections). Would it be possible to have a layer appear taking up the entire window (which would apear above both frames and not appear only in one of them)? I would like to make this layer visable, and then when the layer spawns, there will be an option to hide the layer to again show the frameset within the window.

I seem to only be able to have the layer appear in one or the other frame, but not over both frames.

Any info, as always, will be greatly appreciated!

Thanks in advance!,
