Typo in the PECULIAR ASIDE. It would normally be:
form.form_action[0].value
not:
form.form_action.value[0]
Doh!
Don't want to distract my own thread here, but what's still peculiar is that
form.form_action.value = "whatever"
....(without the [0]) has the desired effect, even though there are multiple
form objects with that name. It still works without the hidden field. Still
odd, or I'm doing a brain blank again.
