Summing a 2D list

Hi all,

I have a scenario where I have a list like this:

User            Score
1                 0
1                 1
1                 5
2                 3
2                 1
3                 2
4                 3
4                 3
4                 2

And I need to add up the score for each user to get something like
this:

User            Score
1                 6
2                 4
3                 2
4                 8

Is this possible? If so, how can I do it? I've tried looping through
the arrays and not had much luck so far.

Any help much appreciated,

Mark
