iCal Integration

[Layton]

I am new to Filemaker and am using Business Tracker to develop a customer management DB for my business. I would like to add the capability of scheduling an appointment, with a displayed contact , from within FM, that would use iCal as the calendar program. (Much like the Email script included with Business Tracker uses Mail) Can anyone point me in the right direction of how to do this? Is there a plug-in that would make this easier? Thanks much!
