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
