thnx YUAN 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.

The request.form variable is set either through input fields in an HTML form or parameters in the URL. Normally you don't have to set it explicitly in your ZTP template.

Do you have a field named 'districtname' in your form? If yes and if the 'action' attribute of the form points to your page template, then the 'districtname' variable should be available.

You can check what varialbes are in the request.form by writing a test template, like test.pt, with the content:

<p tal:content="structure request" />

and then point the 'action' attribute of your form to 'test'. If 'districtname' is not there, then maybe you should check your HTML code.
