Crystal Reports Custom Sorting of report data

Message

   Hi every one,

I am looking for a very simple solution but its getting bit difficult in crystal report, well in my report I have following title
Country, Project Name, Project Category, Tracking Status, Contract Status

Now I am looking for a Custom sorting by clicking on individual Title,
when you click on title Country report should be sorted by Country and if you click on Project Name then report should be sorted by Project Name and so forth...

I have been trying but can't find any solution, if any one can please help.

Thanks,

in advance.

Mitz.
