These queries work individually. How do I write the UNION to SUM all results?

SELECT SUM(players) FROM `tournament_players` FROM (
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p1_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'
UNION
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p2_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'
UNION
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p3_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'
UNION
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p4_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'

    You are on the right track but with an additional FROM keyword. Try this:

    SELECT SUM(players) FROM (
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p1_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'
UNION
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p2_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'
UNION
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p3_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'
UNION
SELECT COUNT(*) as `players` FROM `tournament_players` WHERE `foursome_1_p4_name` IS NOT NULL AND `tournament` BETWEEN 13 AND 17 AND flight = '8 AM'
) `tournament players`
