I am the webmaster for a charity, and we use Zoho calendars to inform our members of meeting dates, fund raising events, etc.

We previously had a calendar embedded on our membership-only website, and a single calendar showed events from multiple sub-calendars(?), overlaid on the same calendar grid, with one colour for events from the "meetings" calendar, a different colour for events from "fund raising", etc.

I was informed by our chairman this week that the embedded calendar had stopped working, and on investigating I found that you have changed the embed code.  I have updated our site and the calendar is now embedding once again, HOWEVER - I can't see how to show multiple calendars on one grid like I did before.  I can show one calendar OR another, but not several all together.

I can't find any documentation that really explains the embed URL options, or how I might be able to specify multiple calendar IDs within the URL.

Can you please let me know how I can make the new embed code behave in the way the old calendar embed used to, and show multiple calendars in one embedded item?
