Changing Groups

[StevenK]

I've struggled through the setting up of Crystal reports through Delphi 5 code. I am using 4 basic report template and according to the users selection of ordering am setting up additional groups at the top of the report - using the syntax 'AddGroup(0, .....)' so that the additional groups are first. I'd prefer to use an alternate method such that I replace the upper-most leading group with a differently specified one - can anyone help ?

Thanks in advance.
