CREATE TABLE table_7501 ("Name" TEXT, "Date of Birth" TEXT, "Height" FLOAT, "Weight" FLOAT, "Spike" FLOAT, "Block" FLOAT)

What is the sum of Spike when the Weight was more than 84, and Block was less than 315?
SELECT SUM("Spike") FROM table_7501 WHERE "Weight" > '84' AND "Block" < '315'
SELECT SUM("Spike") FROM "table_7501" WHERE "Block" < '315' AND "Weight" > '84'
