Polar RS100

I just got a Polar RS-100 and am having trouble with viewing the workout summaries.

When I go to File, it shows me the date of my "last" workout....and allows me to scroll through the information for that workout, such as total time, calories, heart rate, etc. But what about last nights workout? And the day before? Is the prior information lost?

I am confused because it gives me an accurate "grand total" for calories burned thus far.

Is there a way to scroll through the DATES of the workouts and view the details?
