[Zope] Understanding dtml and/or its variables

[Damir Bartakovic]

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
