I had the similar problem when I tried to work with
select box allowing multiple selections. I had to use square brackets too.

ex.: <select name="keywords[]" multiple>
     ...

To reference it in JavaScript I enclosed the name in
single quotes and used it as an index to the elementscollection, as
follows:

   variable=document.forms[0].elements['keywords[]'];

This worked. You can experiment with that, I hope that will help...

Good luck,
Dmitri
