No they do

I had it three times when I was opening chests and the time before that, when I didn't use any chests, I did it exactly the same way and then had no problems

for example when you have the two numbers 2 + 3 for door 3...you'd get 5 right??? well then later on the hint chest said the code for door 3 was 2?!? (EXAMPLE <img src="/images/graemlins/tongue.gif" alt="" /> ) and I had that same thing three times

Shokkadelic!!!
