I think you're confusing checkboxes and radio buttons.

If you have ten different boxes that can be checked, each will usually 
have a different name, so you can test them with data.getfirst("box1"), 
data.getfirst("box2"), and so on.

While it's true that you can have several checkbox elements with the 
same name, and that the CGI interface will give you a list of such 
values, there's absolutely no need to do so and, as you have discovered, 
it's positively unhelpful in most cases.

With radio buttons, you give each member of the set the same name in 
your HTML and the browser submits the value of only the one that's been 
checked (if one has).
