APEX

I just started playing around with Apex 4.0.2 and I had a question which might be quite basic, so please bear with me.

I created a report and a calendar which displays the same data (from a table) in different format. I want to create a link from the calendar to the report based on the data that is being displayed in the calendar to show more details about the calendar item. In the calendar page, I created a link under Column link and did the following:

SET these items: P2_START_DATE
With these values: 10-Dec-2010

When I click on the link from the Calendar page, it gives me the following error:

Error ERR-1002 Unable to find item ID for item "P2_START_DATE" in application "100"

The Report attribute START_DATE does exist in the Page 2.

How do I accomplish this ? Any help will be greatly appreciated.

Thanks and Happy Holidays !
