Hi! I'm trying to make something work now for a some weeks. But I don't have a idea how I can get that OK. I've already written to this list, but after a review of my message I have to say some additional information: I want to realize something simmilar like "information hiding" in OO-programming context. example: Folder structure: Main |-a |-c |-b In folder c and b is a Method which return some content. In folder a and Main a Method collects with <dtml-in "PARENTS[0].objectValues(['Folder'])"> <dtml-with "_[_['sequence-item'].id]"> <dtml-var Method_in_c_b> </dtml-with> </dtml-in> the information from the subfolder. (That works well.) If I add a Method in Main which tries to collect the Information from its Folders in the same way as the Mathed in folder a some Errors arrive instead of the result I want. Has someone a hint? -Helmut
