Problems using "decode"

Question

What I'm trying to do is: For each employee list the value of all pending orders, the value of all completed orders and the value of all orders issued by the employee.
Using these tables:
Orders
Name
ORD_ID
SUPPLIER_ID
ISSUING_EMP_ID
ORDER_DATE
ORDER_STATUS
Sup_Pro
Name
S_ID
P_ID
CATALOG_NO
PRICE
Here is my query
select o.issuing_emp_id,
sum(decode(o.order_status, 'P', p.price, 0)) pending
sum(decode(o.order_status, 'C',p.price,0)) completed,
sum(decode(o.order_status, 'P + C', p.price,0)) all_orders
from
orders o,
sup_pro p
where o.supplier_id = p.s_id
group by o.issuing_emp_id;
The problem is with the line sum(decode(o.order_status, 'P + C', p.price,0)) all_orders. All it does is display 0, and doesn't actually add anything up. What am I doing wrong?

select o.issuing_emp_id,
sum(decode(o.order_status, 'P', p.price, 0)) pending
sum(decode(o.order_status, 'C',p.price,0)) completed,
sum(decode(o.order_status, 'P', p.price,'C',p.price,0)) all_orders
from
orders o,
sup_pro p
where o.supplier_id = p.s_id
group by o.issuing_emp_id;max
