CREATE TABLE table_43398 ("Season" TEXT, "Games" FLOAT, "Lost" FLOAT, "Points" FLOAT, "Pct %" FLOAT, "Goals for" FLOAT, "Goals against" FLOAT, "Playoffs" TEXT)

SELECT SUM("Goals against") FROM table_43398 WHERE "Lost" = '45' AND "Points" > '68'
SELECT SUM("Goals against") FROM "table_43398" WHERE "Lost" = '45' AND "Points" > '68'
