Hi All, Need Help. I'm currently using SQLSession v 0.2.3, with access database ( I had changed the "value" filed in session_data to item_value and also all sql statements that refer to it). I had no problem generate the session id, but however, I had problem calling session object after I insert it into session_data. I got an error when calling the <dtml-var "SESSION['xxx']">, i got this : Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: upper <!-- Traceback (innermost last): File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 214, in publish_module File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 179, in publish File E:\MYBOOK~2\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 165, in publish File E:\MYBOOK~2\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: add_cart_html) File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: add_cart_html) File E:\MYBOOK~2\lib\python\OFS\DTMLDocument.py, line 166, in __call__ (Object: add_cart_html) File E:\MYBOOK~2\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: add_cart_html) File E:\MYBOOK~2\lib\python\DocumentTemplate\DT_Util.py, line 335, in eval (Object: SESSION['bk_isbn']) (Info: SESSION) File <string>, line 0, in ?
