[Zope] parameter prob remains

[prabuddha ray]

Ya i tried d the test code. its givin the district correctly with 
value.
i sud tell u wat am i doin in the javascript method 'user10()' i'm 
invoking on the onchange() of 1st dropdown list.

function user10(){
 	document.nlogin.user11.value='y'     //for username dummy 
value
         document.nlogin.action="index_html" //this page id
 	document.nlogin.method='post'
         document.nlogin.submit()
}

its still givin that compilation error.

  Error Type
    KeyError
  Error Value
   'districtname'

the tal code i used was

<div tal:repeat="user 
python:context.getDistrictUser(districtname=request.form['districtname'])">
<option tal:content="user/username"></opt

I think wen the page is getting loaded its not finding the 
districtname variable. so have to initialize it for the 1st 
load.
something like
  <span tal:condition="districtname|nothing" tal:omit-tag="">
    <!-- initialize explicitly here -->
</span>
  this is jus fancy. gimme a soln .i'm freaked out.
thanks again.
