I'm tripping over what seems like should be fairly straight-forward syntax. Hopefully someone here can point out what I'm overlooking. Situation: I have a folder that contains a bunch of folders, each of which has a property named "coach_id" that I've created and updated programmatically. Task: I have one user who is allowed to see the contents of all folders. All other users are restricted to folders where they are the Coach (i.e., where their AUTHENTICATED_USER== the coach_id of a particular folder). Approach: I have a DTML method that loops over all the folders and displays a list of folder links for each folder the user is authorized to see. That method works fine when I don't try to limit it by authenticated user name. I use a simple <dtml-in> construct for this purpose: <dtml-in expr="objectValues('Folder')" sort=title_or_id> I placed a <dtml-if> statement inside the <dtml-in> construct. That is where the problem is popping up. My if statement should look like this, I think: <dtml-if expr="(AUTHENTICATED_USER.getUserName() == 'Magic User') | (AUTHENTICATED_USER.getUserName() == sequence-var-coach_id)"> But I get an error from Zope indicating the public variable "sequence" isn't defined? I'm in a <dtml-in> so I *believe* sequence should have meaning. Am I wrong? I tried this with only one logic clause in case the problem was the OR syntax or logic. But this: <dtml-if expr="AUTHENTICATED_USER.getUserName() == sequence-item.coach_id"> produces the same "global variable sequence not defined" error. If i hard-code a name into that same sequence, the operation works but, of course, does not filter on the coach_id. <dtml-if expr="AUTHENTICATED_USER.getUserName() == 'Magic User'"> It seems evident that I'm missing something about how <dtml-in> works. I have believed that in the midst of a <dtml-in> I'm iterating over a sequence that is represented by the built-in Zope variable, "sequence." Evidently I'm wrong. Can anyone help? I feel like I'm just guessing at random possibilities now. Obviously time to raise a white flag. (I have to say, this happens so often with Zope that I often wonder if I'm just too dense to get good at this. I try to read and follow docs, but things just always end up slightly out of phase for me.)
