Problem with select statement

Yes Gnari it works now!
all I had to do in addition to your advice was  alias the sub select:

hardwoodthunder=# select 
player_number,player_name,cum_score,sum(a),sum(c),sum(t) from ( select 
player_number, player_name, cum_score, (select player_points where 
aspect='A') as A ,(select player_points where aspect='C') as C, (select 
player_points where aspect='T') as T from (select
* from player as a,teamshare as b where a.player_number=b.player) as c) 
as B group by player_number, player_name, cum_score;
 player_number | player_name | cum_score | sum  | sum  | sum
---------------+-------------+-----------+------+------+-----
 40            | R. Perkins  |         4 | 0.27 | 0.33 |
 42            | S. Randolph |         2 | 0.54 | 0.66 | 0.8
 42            | S. Randolph |         4 | 0.27 | 0.33 | 0.8
(3 rows)

Now what about the total?  How do I add another column that is the sum 
of a,c,t?

I tried sum(sum(a),sum(c),sum(t)) but it doesn't work.
Thanks,
