Hi all I have a form in ZPT which calls a python script which looks up a database to generate some data. Now, the data needs to appear in the same page in a table if the submit button is used. The problem here is to generate the <form method="post" action="GetProjectWiseDataPython"> further down the selection is made as <select name="ProjectName"> <option tal:repeat="options here/GetProjectsPython" tal:content="options/ProjectName">name</option> </select> </form> This is passed to GetProjectWiseDataPython. At the end of the page I need to put a condition "if data obtained from script" show the data obtained from GetProjectWiseDataPython Now, As I understand I need to tal:define="GotData here/GetProjectWiseDataPython" and later tal:content="GotData/Somedata" This is the error message I get while loading the page. *Error Type: TALESError * *Error Value: exceptions.AttributeError on ProjectName in "standard:'here/GetProjectWiseDataPython'", at line 52, column 1* This is not seen when I do not attempt to display the data. What is the way out ? TIA Chetan
