[Zope] Python script error when tying to manage_addZSQLMethod

Hi can someone tell me why I get this error Error Type: AttributeError Error Value: manage_addZSQLMethod from this python script item_id = "test_DTMLDocument" item_title = "Test DTML Document" item_body = """<dtml-var header>...<dtml-var footer>""" sqlName = "SQL_SELECT_ALL" sqlTitle = "View All" dbName = "dbConn" argumentString = "wid given surname" templateString = "SELECT * FROM clients" context.manage_addDTMLDocument(id=item_id,title=item_title,file=item_body) context.manage_addZSQLMethod(id=sqlName,title=sqlTitle, connection_idÛName,arguments=argumentString, template=templateString) what have I missed? I can get the manage_addDTMLDocument to work ok, but not the manage_addZSQLMethod. Dean
