xforms select trouble

[ClarkePeters]

I do fine with select1 and textarea, but can't seem to get "select" to work in my xforms (firefox 1.5.0.9 w/xforms ext).

I need to select zero or more of several choices. (more than one choice allowed to be checked)

here's my instance.xml:

<?xml version="1.0" ?>
<test>
<ii id="1">
<qu id="0">
<ans id="1" type="radio"></ans>
<ans id="2" type="radio"></ans>
<ans id="3" type="radio"></ans>
</qu>
</ii>
</test>

Here's my xhtml/xforms file below. I first tried placing
-- ref="//ans[@id='1'] -- (and @id='2', '3')
in each of the corresponding <value> elements. Then I tried placing just ...@id='1' in the <select> element just to see if I might get a string back. But I'm getting nothing. I tried wrapping each element separately into it's own select element but even that didn't work. Any ideas?

?<?xml version="1.0" ?>
