I have to return a list of Incident records.

One incident can have one or more than one problem link to it.

The problem I have is when the incident has more than one problem, it will count the incidnet more than one.

E.g.
The total number of incidents is 2
Incident #     Related Problems
-------------     ----------------------
100                 201
100                 202

I would like the report to display like:
The total number of incident is 1
Incident #     Related Problems
-------------     ----------------------
100                 201, 202

I don't know how I am able to achieve it... I know an array may help, but after a few days, I still cannot figure out...  Hope you may will be able to help me out...

Thanks in advance, guys!

Cheers! :)
