Aslak:

Is this just a homework assignment to learn how to work with 2d
arrays?  Can you state the problem a little more directly?

I may have missed something, but to me it looks like you have 36
checkboxes whose values you want to store.  Based on those "flag"
values you want to make some changes to another 36 element array.  I
still don't see where the 2D array portion creeps in.

So, let's make it smaller.  You have an array of ones and zeros. 
String ones and zeros together and you get a number.  The pattern of
ones and zeros always comes out to only one number.  Let's say you
have 4 flags.  The first one is one, the next two are off and the last
one is on (1001).  If you look at those as binary values you come up
with 9.  How about scanning your list of checkbox values, coming up
with the decimal value and using that to determine.

This may actually work for you as it appears you only care if a set of
three is checked one way or another.  A lot easier to work over things
3 bits at a time, too.

Sorry for the "geek" solution.  It's the best I could come up with.
