[Zope] Re: RE: [Zope] Grabbing specific indexes from an #in

[craigv@jps.net]

Hope I don't seem dense, but could I get a bit more clarification?

Right now I am iterating through like this:
<!--#in "objectValues('Folder')" sort=sort_code-->

... and pulling out certain properties of each folder:
<!--#var "_['some_property']"-->

How do I achieve the same goal while picking the folder at a specific
sequence? For example, I want to display some properties of the folders
at indexes 2, 5, and 7 without iterating through all of the folders. 

Thanks in advance for your help.
