How can I configure a report to create an excel/csv file for the updates in the last seven days and last 60 days. I have edited the xml files to death to get it to work and even development can't get it to work. Anyone?

Here is the xml code that won't work...  This is a 30 day report.   The problem lies in getting the current date.    I have edited the xml files to death to try to get it to work and even development can't get it to work.  Anyone?
