Your issue comes from assigning the same id twice. This is a
non-supported behavior and your page won't validate.

And are you sure you don't want radio boxes? Can a valid entry really be
both AM and PM? If you go with radios, a common name will link them for
selection purposes, and be sure to give unique ids. If you use radios,
there was a great thread about this here a week ago,

Subject: [Proto-Scripty] Checkbox values for Beginners

Newbie here with some very rusty JS experience just getting my head
round the whole Prototype (1.5.0_rc0) thing on IE7 with Lotus Notes as
the backend AND picking up where a contractor left off!

I have simple form with two boxes - AM and PM

<input type="checkbox" name="txtStartAMPM" value="am" checked
id="txtStartAMPM">am <input type="checkbox" name="txtStartAMPM"
value="pm" checked id="txtStartAMPM">pm

and a submission routine that needs to get the value of these to put in
a URL string


Obviously if the box is unchecked we don't need the value. I have
trawled through many sites this afternoon but have had no luck in
finding one that details how to return the values of the boxes. I got as
far as

var startAMPM = $('txtStartAMPM').pluck('checked');

and got stuck. Could someone give a newb a hand please? Many thanks in
