Ok I haven never used conditionals before so I am obviously using it incorrectly, since I keep getting an error result.

Hun1 ? {-1} : {Hun2 ? {-1} : {Hun3 ? {0} : {Hun4 ? {0} : {Hun5 ? {+1} : {Hun6 ? {+1}}}}}}

Basically I have 6 check boxes and the above formula goes into a stat, which I am trying to get a +1, 0 or -1 result in the stat box depending on which box they tick.

The basic idea is that you have several conditions Hunger, thirst and fatigue, each with 6 tick boxes and lets assume they were all ticked at level 5 the overall result would be +1 in each of 3 separate stats or +3 in a single stat but i am not sure if i need to use three stats and then add them in a final 4th stat or can do the calculation all in one go?

Also is it possible to have a group of tick boxes that a linked so that only one of them can by ticked at any one time, so if you tick one box it removes the tick from any of the other boxes in the group?
