Table schema:
CREATE TABLE table_name_19 (goals_for INTEGER, goals_against VARCHAR, goal_difference VARCHAR, club VARCHAR)

Question: what is the goals when the goal difference is more than -3, the club is real avilés cf and the goals against is more than 60?
SQL: SELECT SUM(goals_for) FROM table_name_19 WHERE goal_difference > -3 AND club = "real avilés cf" AND goals_against > 60
