My point exactly! So long as the name of the name[] part is the same
they will be treated as the same "group" of radio buttons.
So here is the long and short; if the name is the same and you specify
an index then names with the same index will be grouped together:
name[1] and name[1] are the same but different group from name[2]. If
you don't specify an index, but the name is the same, then they are
grouped together: name[], name[].
By grouped together I mean that only one of the group can be selected
and therefore successful on submit.
