Technically, there is no .value for select fields. You have to use


and you can save a little script size by using temp variables for
document.name_form, etc.

If this seems a little odd, remember that selection boxes can be
defined to accept multiple selections so a simple .value isn't *that*
appropriate. However, since all other input objects have one it's not very
logical to leave it out altogether - which, I suppose, is why MSIE
provides one anyway.
