[Zope] Understanding dtml and/or its variables

[Philipp Auersperg]

Hi, I know of that problem, it seems that you have an old version of Znolk,=
 
because in the recent versions I have removed the '.' in the field names,=
 so 
your solution for the future is just to download the newest Znolk version=
 (0.1.3d)
from www.bluedynamics.com or www.zope.org.
---------------------------------------------------------------------

for your existing forms in the meanwhile you can help yourself with the=
 following notation:

 <dtml-unless "_['table.name']">

Hope it helped
