subscribing to google calendar for ical
I got the URL for my wife's goggle calendar that I wanted to integrate into iCal. She's shared the calendar with my google email address. When I attempt to subscribe to a calendar and enter the URL, I get the following message:
"A calendar wasn't found on <URL>. Check the URL."
I'm copying the url with the clipboard so there's nothing wrong with it or at least it's accurately what google provided.
Any ideas what the problem might be? Mind you, I've already subscribed to my and her tripit.com calendars successfully.
TIA,
David
