Linking Null position to 3 other to Control Position with Checkbox Constraints

Oh one pice of information i forgot to mention, Null 1 also has the position linked to Null 2 position. That’s why i have to take that into account on the formula

Sorry, I’m completely lost. I wish I could help, but I still don’t understand what it is you’re trying to do. Maybe someone else will chime in with the solution.
