Hi all, I am using ZnolkSQLWizard and it creates output like <INPUT TYPE="TEXT" NAME="table.name"> ... Now I am trying to force the user not to leave the field blank. Usually it works with <dtml-unless "somevariable"> ... once again! ...</dtml-unless> but with <dtml-unless "table.name"> ... I get the error: Error Type: NameError Error Value: table (The Traceback is at the end) Like it seems it don't like the '.'? But for <dtml-var table.name> I'm getting the right value. So what I'm not understanding? How can I solve it and is it a good idea to use '.' in variables? Thanks Damir Traceback (innermost last): File /usr/local/share/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/share/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/share/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/share/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/share/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: html_insert) File /usr/local/share/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: html_insert) File /usr/local/share/zope/lib/python/OFS/DTMLMethod.py, line 172, in __call__ (Object: html_insert) File /usr/local/share/zope/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: html_insert) File /usr/local/share/zope/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: table.name) (Info: table) File <string>, line 0, in ?
