CREATE TABLE table_64056 ("TV Station  ( Operator ) " TEXT, "2005" FLOAT, "2006" FLOAT, "2007" FLOAT, "2008" FLOAT, "2009" FLOAT, "2010" FLOAT, "2011 1H" FLOAT)

What's the 2006 if there's less than 6.7 in 2007 and less than 3.4 in 2009?
SELECT SUM("2006") FROM table_64056 WHERE "2007" < '6.7' AND "2009" < '3.4'
SELECT SUM("2006") FROM "table_64056" WHERE "2007" < '6.7' AND "2009" < '3.4'
