[Zope] calling Python Script from dtml-let

[Bill Seitz]

I have a simple Python Script called passwordRandom().

It works fine if I call it with:
  <dtml-call "REQUEST.set('password', passwordRandom())">

But I want that value to be available for some other things, so I want 
to set a variable with dtml-let.

But if I do:
  <dtml-let password2 = "passwordRandom()">
(with a </dtml-let> further down)

Then I get

invalid parameter: "password = "passwordRandom()"", for tag <dtml-let 
password = "passwordRandom()">, on line 18 of ActivateAccountHack

What stupid mistake am I making?
