[Zope] Help needed: why is this DTML not working in zope 2 ?

[Shane Hathaway]

Hello Gilles,

I think you've been bitten by a recently solved bug in dtml-try.  When
2.2.0b4 comes out, please download it and try it out with your DTML (or
if you're in a hurry, download from CVS.)  If 2.2.0b4 doesn't solve it,
e-mail me right away.
