Accessing multiple List/Menu values

This is sorta OT, but involves PHP. I have a fairly large List/Menu on a form, which allows for multiple selections. I want users to be able to use cntrl/shift-click to select a bunch of items. Let's say this List is called 'list'. Now when I submit the form, how does the processing script access all these different values in 'list'? If I try to echo '$list' it only show *one* of the selected items from the list. I've tried treating it as an array ($list[0], $list[1], etc), but that doesn't work either. How do I get at the different values? Thanks, -- : Joseph Szobody : "Computers are like airconditioners: They stop working properly if you open windows."
