How to create framesets?

Question

Not animation/rollover frames, but actual frame sets...
As per my previous topic in this forum, I made a graphic to
show my situation:

The canvas is 800x600. Everything GREEN cannot be moved
(meaning I do not want to change the layout). I would like a
frameset (might be another way to do it, but it must function like
a frameset) within this area with a scroll bar in it (BLUE)
I tryed adding a "layer" on top of it in dreamweaver, but the
layer did not allow me to keep the size a certain amount. I pasted
some sample text and the result was something like this:

Any possible solutions (keeping in mind I am a total newbie
at web design)?
Thanks again

Answer 1

Perhaps I am understanding something wrong, or perhaps I am
explaining my situation wrong.
Everything you have said so far works the way you explained
it, but here is why it does not work in my situation:
If I set the right value to 20% (for example), than the layer
will be 20% from the right side - which is fine in theory, but as
soon as I grab the right edge of my browser window and resize it
(to simulate different viewing conditions/screen res's) the layer
moves as well (because it is remaining 20% away from the edge). The
result is that the layer moves "on top" of other elements of my
page. The same for the top value - if I set it a certain %, and
move window size smaller/bigger vertically, that layer moves into
my header and even off my canvas if the window is resized enough.
The same thing happens when I set it to use px instead of %.
The pixel value (from the left edge for example) will be 300 px
(example). If I resize my window by dragging the left side into the
center, than the layer still stays the standard 300 px from the
left side - which means my layer starts to move off of the right
side of my canvas.
I hope that gives a clearer image of my situation.
Oh, and thanks again for all the help
EDIT Here is a little animation I made that shows the
problem by simulating different browsing sizes. Color Red is my
menus/headers etc. Blue Gradient is my background (behind my
canvas). The little text block in center is my Layer. Black is
outside of the window area.

This is with my right value set to an X number of pixels. But
the situation would be similar if I set it to have a left px value,
or a left/right % value (only it would move the other way).
