-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Are you checking for a checkbox?

Hi,
From the 'Zope Book' the statement
<dtml-if variable>
means that 'if the..variable does not exist, then this condition is false'.
I found that this is not true. When I tried using dtml-if to a non-existent variable, I got a 'key error'. So how do I check if the variable does not exist ?
Tks.
