I am just started to use Crystal Reports so I am a begginer. My question is:
I need to create a field that counts the people (not the records) in my report. The problem is that some persons may be presents more than once.

ID Name
32 George
32 George
35 John...
In the report I group records by Id, in detail band I must have fields that count person

1 32 Geogre ...
32 George ...
2 35 John etc.

How can I do that?
