[Zope] dtml-in

Hi; I'm sure this code is terribly botched, but I've been to the DTML Reference and didn't find any help there. Here's my code: <dtml-in "All_Seminars.Basic_Structural_Concepts()"> <select> <dtml-let field=sequence-item> <option><dtml-var "field.render()"></option> </dtml-let> </select> </dtml-in> All_Seminars is a folder and Basic_Structural_Concepts is nested within that folder. Within the latter are a series of dtml methods I would like to iterate through as options within the <select> tag. Can someone tell me how to do this and/or point me to a good tutorial on the subject? TIA, BenO
