Ok, maybe second time will be better replace 'EXT:kopbsurveyext/class.kopbsurveyext.php:tx_kopbsurveyext'; with 'tx_kopbsurveyext'; because you just included kopbsurveyext/class.kopbsurveyext.php with require_once(t3lib_extMgm::extPath('kopbsurveyext').'class.kopbsurveyext.php'); -- З повагою, Бойчук Петро
