Revise existing Flash calendar file

We have an existing fla file for an event calendar. We want to add small graphic icons to the squares in the area of the montly layout. The event calendar that we are using uses data from an xml file that we update. We need to put the links for the graphic icons in the external xml file. You can see a similar Event calendar at: [login to view URL] The clock in the square gives you an idea of what we want. Thanks.s
