Interactive sorting to matrix report in reporting services 2005

i want so active a interactive sort on the last columns that named 'Matrix1_ObjName'.

I never use interactive sort. When I want to be able to change sorting behavior, I do it with a parameter. Create a new report parameter and specify values. Use something descriptive for the labels, then I use integers beginning at zero for the values. After the param is set up right click on a field in report design and go to Row Group then Group Properties. Select Sorting from the menu and build an expression with an if statement similar to this:

=IIf(Parameters!sort.Value=0,Fields!First_Sort.Value,Fields!Second_Sort.Value)

Might help you.
