[Zope] Defining a dictionary in ZPT?

Hi I've got this piece of code which is returning a keyerror on 'results' as I haven't set up a dictionary for the variables. I'm not sure what the syntax is for this within the ZPT. I've read about the 'options' dictionary. Can I use that? Thanks <ul> <span tal:define="query here/testquery"> <li tal content="results python: query(id='IT')"> <span tal:replace="results/firstname">First Name</span>  </li> </span> </ul> -- michael
