Don't use the column name aliasing and it should work: 
select sum(tickettab.tokenid) + 
(select sum(tokenid) from ticketmultab
where agentid='danny' and arrivaldate='2001-11-12') 
from tickettab
where tickettab.agentid='danny' and
tickettab.arrivaldate='2001-11-12' ;

What is so mysterious about your join? 
To answer your question, it would be very helpful to see the query 
instead of reading prose.
