Driver Tree

Hello!

I have a BIG problem that I hope some of you cool guys can help me with.

I have something like this driver tree where I want to run a test if it's filled out correctly.

The point is that you have to specify on the same level. If I choose (x) level 1-1 I can't choose something witch is under that same level. That means 1-1-xxxx
Also if i choose 1-1-2-1 I have to choose the other three on that same level. If not choosen there should be a mistake all the way up in the tree.


The tree below is not correct specified. Lets say state 1 is correct and 0 is wrong.

State    V-level    Driver                                    choose
0      1    Revenue                   
0      1-1        Net production               
1      1-1-1            Gross production      x   
0      1-1-2            Production Losses      x   
1      1-1-2-1                Non-array losses  x   
1      1-1-2-2                Array losses      x   
0      1-1-2-3                Park availability
1      1-1-2-4                Other Adjustments x   
0      1-2        Prices               
1      1-2-1            Power           
1      1-2-1-1                Gross prices       x   
1      1-2-1-2                Adjustments      x   
0      1-2-2            Subsidies           
1      1-2-2-1                Sub2              x   
0      1-2-2-2                        Sub1


Really hope it makes sense otherwice write!

Thanks in advance
