Fine so far. As we go on, remember that container is bound to the 
folder that contains the script. It doesn't change (unless you
were to explicitly bind something else to the name "container")

ok, folder now refers to container.folder01

> folder2,'')

you have now created container.folder01.folder02...

> folder=container[folder2]

container still means the container of the script. That's not
where you put folder02!  YOu're asking for container.folder02 and there
is no such thing.

You could instead get to the new folder this way:

folder = container[folder1][folder2]

... but that's unnecessarily long; you've already got folder = 
container[folder1] so it's perfectly valid to use that like so:

folder = folder[folder02]

folder.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder3, 
 folder3,'')
folder = folder[folder3]

... and so on.

Once you have it working, your next assignment is to figure out
how a single "for" loop would make this script a whole lot shorter and
easier to maintain. :-)
