sql syntax error creating trigger

Question

I want to create trigger and I have written this query but this does not execute. Please check my query

CREATE
    TRIGGER 'blog_after_insert' AFTER INSERT 
    ON 'blog' 
    FOR EACH ROW BEGIN

        IF NEW.deleted THEN
            SET @changetype = 'DELETE';
        ELSE
            SET @changetype = 'NEW';
        END IF;

        INSERT INTO audit (blog_id, changetype) VALUES (NEW.id, @changetype);

I am getting this error
