Counting

[David Harrison]

How would I tell javascript to display a list of numbers depending on certain factors (subject to change) that I can specify such as:

* whole numbers
* divide by "x"
* are between "y" and "z"
* anything else that you think might be useful that I can't think of now.

This does help quite a lot, don't get me wrong, but how can I modify the script you gave to do the following:
* Count down from a certain number rather than up.
*Instead of appearing in a textarea, appear in a new pop-up window. (I have very limited experience with forms).
