Table schema:
CREATE TABLE table_name_68 (total VARCHAR, nation VARCHAR, rank VARCHAR, gold VARCHAR, silver VARCHAR)

Question: What is the total number of Total, when Gold is less than 1, when Silver is greater than 0, when Rank is 14, and when Nation is Afghanistan?
SQL: SELECT COUNT(total) FROM table_name_68 WHERE gold < 1 AND silver > 0 AND rank = "14" AND nation = "afghanistan"
