Help with converting 2007 pivot to work on 2003

Hello,

I created a report in Excel 2007 with pivot tables. However, I just found out that the people that will be updating it are on 2003. As a result, none of my pivot tables will work. Can someone please take a look at the attached spreadsheet and give me some guidance on how I can get this to work in 2003? I would like for the pivot tables to update with the added data when refreshed but not sure how to do that either in 2003.
