Hi to all.
Can someone help me?
I would like to create a report to compare sales for a company. For example they  want to put  in creteria  a range of date(2011-02-03 /2011-03-03) and in two tables they would like to have the values from 2011 and  the exactly dates from previus year.
It would be like this:

date range from 2011-02-03 to 2011-03-03

                         (2011-02-03 to 2011-03-03) (2010-02-03 to 2010-03-03)
sales                         5.000                               6.000

Thanks a lot.It works!
