several SUMs in one query each using different tables

[sqlhelpme]

I know how to get a sum in a query, but I need several different sums with different where clauses all in one query. Is that possible?

I.e. want, region, code, name, sum1 (from tableA where 1,2,3), sum2 (from tableB where 2,4,5)

I can only get 1 aggregate function to work per query.

select regionNumber, code, officename, sum(amt) as sum1
from projects p, ProjectActualCosts ac, actualCostTypes a, ProjectActual393 pa , cans c, vwoffices vw
where ac.actualCostTypeID= a.actualCostTypeID
and a.actualcostTypeIsPartOf <> 10 and pa.projectactualid = ac.projectactualid and
pa.projectid = p.projectid and
p.canid = c.canid and
vw.Officecode = p.doc and
[393date] between @BuildFY and @thisMonth group by regionnumber, code, officename

your help is appreciated. Thanks!
