Creating a Calendar in CS3

Hi, I’m a teacher and I’m trying to create an interactive calendar in CS3 for my class website. I want to put the calendar on the left so that when you click on a date, a window will open up on the right that will display the day’s lesson.

I found a tutorial but it’s in an older version of ActionScript so I keep getting an 1105 error when I try it.

Is there anyone out there that could help me or point me in the right direction ???
