Also, I cannot use grouping

Actually my report is something like this:
# ID   Country   Contact
1 a102 USA       tom wang
2 a102 USA       kim pitt
3 a102 USA       chelsea
4 b104 USA       curtscott
5 b104 USA       rob da silva

and i have to display it as :

1 a102 tom
       kim
       chelsea
2 b104 curt
        rob

each record has a field called contact which can have more than 1 name... but except for the name everything else needs to be suppressed and records number should be distinct for each distinct ID.

HELP!
