PL/SQL Error

I was trying to implement a trigger
 CREATE OR REPLACE TRIGGER answer_view_Trig  AFTER UPDATE ON MON_Answer
 begin

      CREATE OR REPLACE VIEW Answer_View 
	AS (SELECT A.MQ_ID, A.MQ_Number, A.MQ_Question, A.MP_ID, A.MQ_Type,  
                 B.MA_ID, B.MA_Answer, B.ME_ID
	    FROM MON_Question A,
		   MON_Answer B
	    WHERE  A.MQ_ID = B.MQ_ID)

and received the following error.

PLS-00103: Encountered the symbol "(" when expecting one of the following:

   begin declare exit for goto if loop mod null pragma raise    return select update while <an identifier>    <a double-quoted delimited-identifier> <a bind variable> <<    close current delete fetch lock insert open rollback    savepoint set sql commit <a single-quoted SQL string>

Can someone point me in a direction as to how to fix this error.

                Thanks,
