Java Scrpit

[Heian]

Anyone here good with Java script? My roommate is a CS major and needs a little help with a project.

From him: "Basically, it's a simple tree of information where information that is selected on the lower segment can't be displayed at the top. Say I have a bottom row from 1->10 (1, 2, ..., 10). Someone selects '7' with a radio input type, and the row above that will have 1, 2, 3, 4, 5, 6, 8, 9, 10. Basically, it's the same thing all the way to the top until we reach the last one. If something changes on a level below a row, we can just erase all the data in that row. Make sense? I'll be back if it didn't "

Do you have a friend who's an English major and can help translate his description?

Well since you can only make fun of my roommate's grammar then I'm guessing you know nothing about Java Script.

Ok, his roommate here again. Here's a refined description:
I have 10 SELECT fields, or drop down menus. Each field originally contains the same options. If one field is selected as "foo", we have two options (whichever you think is easiest or more feasible to do):
* One. Once that selection (say, "foo") is selected in one drop down, every other drop down has that entry removed from it. Of course, if the original dropdown is changed, the option will reappear in every other drop down menu.
* Two (and I think this will be the easiest). If the user selects the same value in another drop down menu, it will either not allow him (ALERT) or change the original drop down menu to NULL.

Make sense?
