[Zope] DTML Newbie: Using variable as an object in path?

[Patrick Price]

I'm lost. I have a folder, channels, and inside that, an RDF Summary 
object named slashdot:

<dtml-let channel="slashdot">
<dtml-with "channels[channel]">
   etc...
</dtml-with>
</dtml-let>

This results in "Global name 'slashdot' is not defined."  

An interesting aside:  if I try <dtml-with "channels.[channel]"> the 
source will refuse to save, I get "page not found" when I click Save 
Changes.

What am I doing wrong?
