thanks for your response. I'll have to clarify my question. What I'm looking for is a query script that imports a puble calendar file into trumba from a third party website. I'll use the script of Googla calendar is an example. For Gcal this is script is: http://www.google.com/calendar/render?cid= if I then add a public ical address to this script eg http://ical.mac.com/rutgergeelen/All.ics then this results in http://www.google.com/calendar/render?cid=...rgeelen/All.ics. If I put this scirpt on my webpage and a visitor clicks this link it opens his/her google calendar and imports the public calendar. What I'm looking for is the first part of this script for Trumba.
