Table schema:
CREATE TABLE table_name_31 (fall_05 VARCHAR, fall_09 VARCHAR, states VARCHAR, fall_08 VARCHAR, fall_06 VARCHAR)

Question: What is the sum amount of fall 05 when fall 08 is more than 5, fall 06 is more than 7, the state is Maryland, and fall 09 is more than 471?
SQL: SELECT COUNT(fall_05) FROM table_name_31 WHERE fall_08 > 5 AND fall_06 > 7 AND states = "maryland" AND fall_09 > 471
