You're a star!  That's exactly what I needed to do.
You think that having used XSL for n years, I would
be used to adding a $ to the variable name...

Hi Derek,

now while trying out your code I discovered something that really has
nothing
to do with CForms:

<jx:forEach var="thisTheme" items="atheme">
<li>A Selection 1: ${atheme}</li>
</jx:forEach>

the syntax is simply wrong. it should say

<jx:forEach var="thisTheme" items="${atheme}">
<li>A Selection 1: ${thisTheme}</li>
</jx:forEach>

now this should help ;)
