Crystal Report 2011 Grouping

Hi Guys,

I'm trying to create group reports but i'm having problem sorting them properly.

i have 3 different groups.

Group A, Group B and Group C

i want the report to appear like this-

Group A

Group A

Group A

Group B

Group B

Group B

Group C

Group C

Group C

But my report doesn't seem to appear like that. My report is showing as :

Group A

Group B

Group C

Group A

Group B

Group C

Group A

Group B

Group C

How can i fix this?

Thank you very much in advance.
