[hiscores]

There should be no dashes and date or times, you also need to use two equal 
signs to test for equality:


bi1=ValueWhen(DateNum() == 1070101, bi);
bi2=ValueWhen(DateNum() == 1071201, bi);

As per the documentation: 

"10000 * (year - 1900) + 100 * month + day, so 2001-12-31 becomes 1011231 and 
1995-12-31 becomes 951231 "
