Rails - Jul 2006 - 2 ActiveRecord Calculations

Hi, I am trying to use active record calculations to perform two 
calculations.

1. Get the sum for each group.
2. Of those groups, find the maximum number of that sum


I have the first step done, I just can''t figure out the second step. 
Any ideas?

Here is what I have right now:

@total_points = BlahPoint.sum(''value'', :group =>
''blah_id'')

Then within my view I am calling:

@total_points[blah.id]

So as you can see, I have total points for each group (blah_id) and now 
I am trying to figure out how I can access the group with the most 
points.

Thanks in advance.
