Ok, im desperate, i have been stuck on the logic mission 5 of hackthissite for over a Month now, i cannot do it. I figured at least some people on newgrounds will have heard of this site, and some will have solved it. If you know the answer please help me, it's driving me crazy.

For those of you who haven't heard of it but want to try, here is the riddle:

There are two halves to this mission! Try the first one first.

There is a box then to put the answer in.

Any help will be very much appreciated. :D
