Interactive Sort in Matrix

Hi,

I making a report using Matrix with 2 row groups and 1 column group. The group names are:

Row : CompanyName, TotalUsers

Column: UserType

Detail Group has a count of number of user in each type.

I want to use interactive sort feature on my column group so that when I click on my column header, it sort my detail group data ascending or decending and companyName and total users based on datail group.

Thanks a lot,

-Rohit

I tried different options for the scope but non of them works. Does any one know how to do this?

Thanks.
