last year I was using the code found here http://gdata-javascript-client.googlecode.com/svn/trunk/samples/calendar/simple_sample/simple_sample.html to retrieve all events from now of a public Google Calendar and then display the results in a webpage.
I modified that code to match my needs (see the code below).
Now, with API v3, the code doesn't work anymore and I'm not able to understand which lines of the code are deprecated and how to update them.
Could please someone help me with this code?
Thank you so much :-)
