Multi column update

Hi all, I'm trying to write where appears to be a simple query but can't get it right.
Here's the intent.
update A set (a1,a2,a3) = (select sum(b1),sum(b2),sum(b3) from B group by b4 where B.b4 = A.A4)
I got two tables, A and B. The join parameters are A.A4 and B.B4. I need to updated a1, a2 and a3 in A to equal the sums of b1, b2 and b3 in B. The sum needs to be grouped by b4 and A.a4 needs to equal B.b4.
Can someone help?
