finding sum of values found from a query

I have a query which returns two rows of data as count. I want to find sum of the column values. My sql:

(SELECT count(memberid) count 
   FROM `friendRequest`, Member 
   where status = 2 and memberid = sender and receiver = 19) 
UNION 
(SELECT count(memberid) count 
   FROM `friendRequest`, Member 
   where status = 2 and memberid = receiver and sender = 19)

I have tried using Select Sum(my above query) but I am getting error. I just need some of above values.

Answer

Can grab both result sets in a single query:

SELECT count(memberid) count 
FROM `friendRequest`, Member 
WHERE status = 2 AND (
    (memberid = sender AND receiver = 19) OR 
    (memderid = receiver AND sender = 19)
)
