Hi everybody, I know this is a ricurrent newbie problem, and I have been searching the ML archives, but yet I could not solve it. How can I pass a parameter from a python script to a Zsql method ? I want to perform a very basic multiple value query on a database through the sql "select where in" command. I would split the REQUEST into a list, and then pass it to a Zsql method. I have the following Dtml document (named "form_itemSearch") : <form action="search" method="get"> <p>Please enter the following information:</p> Code : <input name="code:string"><br> <input type="submit" value=" Search "><br> </form> Then I have the following "search" dtml document : <dtml-call "process_input (code)"> <dtml-call "search_Item (code2=code1)"> And this is my "process_input" Python script (parameter :code) : import string code1 = string.split(code) return code1 And my "search_Item" zsql method (argument: code2 )is : select * from items where code_item in (<dtml-sqlvar code2 type=string>) If I call the first "form_itemSearch" from the web, I get the following error : Zope has encountered an error while publishing this resource.
