Thank you for your post.
iCal only imports iCal files, vCal files and Entourage data; neither of which FileMaker exports. The only other possibility is to export the information to a CSV or Merge text file, and then import that data into Bento, which integrates directly with iCal. You can download a 30-day trial from our web site at www.filemaker.com and see if this works for you.
I appreciate the bento tip, I have bento and will try that. I guess I could also export the file and download it to my google calendar that is synced up to my ical.
Thanks again for replying and providing solutions to my posts.
