The Xron product, did the trick. Xron is a product that allows a timed event to be triggered internal to Zope. What I did was; install the product, and add an instance. This places a schedule object (Z Catalog I think) in your site root, and and Xron DTML method wherever locally you want it. Give it an ID, Execute At (starting time, in some time format Zope understands), and Reschedule Interval (nightly in my case). Then add dtml to the method (in this case a method that calls a python script that calls ZSQL directly.) It seems to work very well. Now a question. How stable is Xron? It still seems to be in development. Harlow Pinson Indepth Learning Email: hpinson@indepthl.com Web: http://www.indepthl.com Voice: 505-994-2135 FAX: 208-475-7678
