Table schema:
CREATE TABLE table_name_21 (height VARCHAR, name VARCHAR, spike VARCHAR, block VARCHAR)

Question: What is the total number of Height(s), when Spike is less than 352, when Block is greater than 300, and when Name is Pablo Meana?
SQL: SELECT COUNT(height) FROM table_name_21 WHERE spike < 352 AND block > 300 AND name = "pablo meana"
