[Zope] Re[2]: [Zope] comparing variables from different name spaces?

[Ainis]

Hello Chris,

Well, it almost worked. I had to use <dtml-var "PARENTS[-3].id">
but now I have another problem. This variable does not exist when i
make requests in /test/ folder (which is normal, as /test/ has no
such parents), in /test/dir2 it works fine.
So I tried:
<dtml-if "PARENTS[-3].id">
but i get an error if it does not exist. So how do i check if the
variable exists?
