Hi, It does contain nc_report_no from the first form that prompts for this information. I do not have nc_report_no set global. I have the ZSQL query looking for the input without the ':string="%"'. The user will add their info to the next form and I write the record. Most times they will have several of these records. I provide a link to back to the previous form. But if I go back, the <dtml-in> call needs the value of nc_report_no. If I add the global syntax in than the user the first time through will error. The error message would be that the variable was not globally assign yet. If I have the form setup this way: <dtml-call "REQUEST.set('nc_report_no', REQUEST.SESSION['nc_report_no'])"> <dtml-call "REQUEST.SESSION.set('nc_report_no', nc_report_no)"> <dtml-in lookup_nc_report_no_query> I get this traceback Traceback (innermost last): File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 150, in publish_module File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 114, in publish File C:\PROGRA~1\proton\lib\python\Zope\__init__.py, line 158, in zpublisher_exception_hook (Object: backup_partb) File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 98, in publish File C:\PROGRA~1\proton\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: update_nonc_partb) File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: update_nonc_partb) File C:\PROGRA~1\proton\lib\python\OFS\DTMLDocument.py, line 127, in __call__ (Object: update_nonc_partb) File C:\PROGRA~1\proton\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: update_nonc_partb) File C:\PROGRA~1\proton\lib\python\DocumentTemplate\DT_Util.py, line 159, in eval (Object: REQUEST.set('nc_report_no', REQUEST.SESSION['nc_report_no'])) (Info: REQUEST) File <string>, line 2, in f File C:\PROGRA~1\proton\lib\python\AccessControl\DTML.py, line 32, in guarded_getitem (Object: update_nonc_partb) File C:\PROGRA~1\proton\lib\python\AccessControl\ZopeGuards.py, line 90, in guarded_getitem File C:\PROGRA~1\proton\lib\python\Products\Transience\TransientObject.py, line 135, in __getitem__ KeyError: (see above) If I remove the lines before the <dtml-in> I will get this traceback the second time through - Missing input variable, nc_report_no Traceback (innermost last): File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 150, in publish_module File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 114, in publish File C:\PROGRA~1\proton\lib\python\Zope\__init__.py, line 158, in zpublisher_exception_hook (Object: backup_partb) File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 98, in publish File C:\PROGRA~1\proton\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: update_nonc_partb) File C:\Program Files\proton\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: update_nonc_partb) File C:\PROGRA~1\proton\lib\python\OFS\DTMLDocument.py, line 127, in __call__ (Object: update_nonc_partb) File C:\PROGRA~1\proton\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: update_nonc_partb) File C:\PROGRA~1\proton\lib\python\DocumentTemplate\DT_In.py, line 617, in renderwob (Object: lookup_nc_report_no_query) File C:\PROGRA~1\proton\lib\python\Shared\DC\ZRDB\DA.py, line 414, in __call__ (Object: lookup_nc_report_no_query) File C:\PROGRA~1\proton\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: <string>) File C:\PROGRA~1\proton\lib\python\Shared\DC\ZRDB\sqlvar.py, line 99, in render (Object: nc_report_no) Missing Input: (see above) -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: Monday, November 11, 2002 2:01 PM To: McDonnell, Larry Cc: 'Zope@Zope.

I cannot tell you why. Look at the traceback. It should tell you where exceptions are raised. Dieter
