I have an idea for you.  Rewrite in python.  Its easy to return a html 
<select> structure from a python scripts and python scripts are so much 
easier to think thru than dtml. 

Then from your dtml (if i recall)  you'd just <dtml-var 
expr="yourPython()">.  From tal use include the "structure" key word like:
<span tal:content="structure python:context.yourPython(params= ...)  

If you get stuck re-ask (but give your version in python code) :-)
